Modifying the VRChat client is not allowed by VRChat Terms of Service and can lead to your account being banned.
Based on evidence until this point, VRChat Team will happily hand out bans to people using mods with evil features, such as ripping, crashing, and others things you don't want to be on the receiving end of. Mods published here aim to avoid negative attention from VRChat Team and hopefully keep their users in a non-banned state as long as possible.
However, with that said, these mods are provided without any warranty and as-is. If you use them and do get banned, don't complain to me that you were not warned. Also, report your ban to VRChat Modding Group discord (see above) - every data point matters in determining how safe mods are for general public use.

As an extra point, if you encounter an issue with the game (especially after an update), make sure that issue is not caused by mods before reporting it to VRChat Team. You can add --no-mods launch option (in Steam) to temporarily disable MelonLoader without uninstalling it completely.

Some mods will have Canny tickets linked. It's your duty to go and upvote them to show to VRChat Team what you want from their game. If you decide to comment on Canny, be respectful and avoid mentioning modding - the team still doesn't like it, obviously.
And yes, it will probably be ignored/forever hanging in "under review" like the majority of Canny posts. At least we'll have a nice big upvote number on our ignored posts.



  • Set hard limits on avatar features, such as polygon count, audio sources, and some other things
    • Reduce crashes
    • Improve performance
    • Remove annoying spawn sounds or global sounds
    • Remove some fullscreen effects (this one is unreliable)
    • Avatars over the limit are not replaced by a gray robot. Instead, elements over limits are removed, with the rest of the avatar kept intact.
  • Hide all avatars of a specific author (requires UI Expansion Kit, button is in user details menu)
  • Hide a specific avatar, no matter who uses it (requires UI Expansion Kit, button in in user quick menu)
  • Hide portals from blocked users or non-friends
    • That blocked user will no longer be able to portal drop you

This mod will introduce small lag spikes when avatars are loaded. These should be tolerable compared to VRChat's own lag spikes.
All numeric limits are configurable.

  • Don't set animators limit to 0 - you will break all humanoid avatars horribly if you do

Configurable for friends and vanilla "show avatar" button.

Allows resizing the camera, zooming it in/out and hiding camera lens.
This is a lazy rewrite of original VRCCameraPlus by Slaynash.
Requires UI Expansion Kit - new buttons are added to Camera expando (collapsed by default, click the small blue square near camera to expand) or to Camera QuickMenu expansion (can be chosen in mod settings).

  • Freely changeable list height
  • Avatar, world, and player favorites supported
  • Modifiable list order and multiple list sorting options
  • Fully searchable database of everything you have ever seen
  • Changeable database location (it's recommended to store the database in a directory backed up to cloud storage, such as Dropbox or OneDrive, see below for setup)
  • Local image cache for even better performance
  • Categorize your own private avatars
  • Import avatar favorites from other local favorite mods (read below)
  • Exchange search database with friends (read below)

  • Many more small things

Known limitations

  • Player favorites don't show online status
  • Lists with over a thousand elements can take a bit of time on game startup/list creation

Canny tickets

Changing database location

Steps to change database location:

  1. Run VRChat with the mod at least once
  2. Make sure that VRChat is closed
  3. Navigate to VRChat install directory (i.e. by clicking "Browse Local Files" in Steam)
  4. Navigate to UserData folder and open MelonPreferenes.cfg with Notepad or other text editor
  5. Find the line with [FavCat]
  6. Find the line with DatabasePath under it
  7. Change the value to absolute path to new storage folder. The new line should look like this: DatabasePath = "C:/Users/username/OneDrive" (with your own path, naturally; make sure to use forward clashes / instead of backslashes \\)
  8. Save and close the text file
  9. Copy the two (or four) database files (favcat-favs.db and favacat-store.db, and favcat-favs-log.db and favcat-store-log.db if they exist) from the old location (they are in UserData by default) to the new one.

If you want to move the image cache, use the same steps as above, but modify the line with ImageCachePath and copy favcat-images.db instead. It's not recommended to store the image cache in cloud storage due to its big size.

Sharing search database with friends

You can exchange the search database with friends to be able to find things they have seen. Only accept databases from friends you trust - an intentionally malformed database can overwrite parts of yours with garbage
How to send database to a friend:

  1. Run VRChat with the mod at least once (duh)
  2. Make sure that VRChat is closed
  3. Navigate to where your database is stored (see "Changing database location")
  4. Make sure that there is no file named favcat-store-log.db. If there is one, it means that the game was not closed properly. In that case, run the game again, and use "Exit VRChat" button in settings menu to close it.
  5. Send favcat-store.db to your friend.

How to receive database from a friend:

  1. Run VRChat with the mod at least once
  2. Navigate to VRChat install directory (i.e. by clicking "Browse Local Files" in Steam)
  3. Put the database your friend sent you into UserData/FavCatImport folder. If you want to import multiple databases at once, you can rename them, as long as .db extension is kept.
  4. In-game, click "More FavCat" on any big menu page, then click "Import databases and text files"
  5. Import process can take some time. Once it is done, the corresponding database will be deleted from UserData/FavCatImport folder.

Note that your favorites are stored in favcat-favs.db - don't send it to your friends, favorite import is not supported. Most certainly don't send favcat-images.db to your friends - it's just a boring image cache.

Avatar favorites deprecation

Due to recent events surrounding modding (modder ban-unban wave, VRC Team/modders discussion, API changes), I've decided to remove extra avatar favorites from FavCat.
One of the biggest concerns raised during the still-ongoing discussion between modders and VRChat Team is mods stepping on VRC+ features. VRChat relies on VRC+ supporters to pay for servers and ensure that VRChat continues existing.
As such, I wanted to proactively address that concern. One of my main goals with modding VRChat is making the game better for everyone, and negatively affecting the platform itself goes against that.
I believe this step to be necessary to ensure that VRChat team sees (wholesome) modding not as a threat, but as an opportunity.
On top of that, recent API changes indicate that VRChat Team is taking action to restrict access to avatars. It might be an attempt at ripping prevention, or it might be aimed at privacy enhancement, or it might be aimed at extended avatar favorites. There's no way to tell for sure, and there's no knowing how far those changes would go in the future. Local favorite mods have to rely on the API to some degree, and with things changing quickly, there's no reliable way to ensure that things will stay working and stay safe ban-wise in the long run.

Before you read on, please scroll up a bit and upvote all linked Canny tickets related to avatar favorites. If you decide to comment on them, remember to stay civil and avoid mentioning mods.

In more practical terms, this means the following:

  • Starting with this update, you will not be able to add new avatar favorites, create new avatar favorite lists, or import avatar favorite lists
  • Starting on 2021-05-31, you will not be able to access your existing avatar favorite lists in-game
  • Avatar search will stay accessible for the time being.
  • World and user favorites will stay accessible for the time being.
    VRChat Team did mention during the recent dev stream that they are going to provide additional player and world favorites for everyone at some later point.
  • You can export all your favorites into plain text files from "More FavCat..." menu in the respective menu page. Exported lists are put in UserData/FavCatExport folder. Export will be always available and is not subject to time limits mentioned above.
    This has limited usability, but you probably can put them on pedestals in your own world or find an udon world that has change-pedestal-to-id function (unless that gets restricted eventually).
    This is still somewhat iffy, but it's unwieldy/uncomfortable enough compared to in-menu favorite lists that I wouldn't consider that as a viable replacement for VRC+ extra favorites.

Q1: But what about another mod X that still offers unlimited avatar favorites for everyone?
A1: Good question! If that is a VRCMG mod, it'll likely follow suit.
If it's not a VRCMG mod, if I were you, I'd be extremely wary of that. Those mods are unverified in VRCMG, and usually for a good reason.
There have been numerous cases of unverified mods being harmful towards their own users. After all, if one makes a mod to harm other users and/or VRChat itself, who says that they wouldn't want to harm its own users eventually for some petty reason?
Additionally, consider this: recently there was a relatively big ban wave against users of a certain malicious/unverified mod. It's not too hard to imagine that another malicious/unverified mod will be next.

Q2: Does that mean that mods are now okay if they don't touch VRC+?
A2: Nope! According to VRChat Team all mods are still against Terms of Service and therefore bannable, nothing has changed there.

Q3: Why only remove avatar favorites, but not world and/or player favorites?
A3: Simply because extra world/player favorites are not a VRC+ feature.
If, for whatever reason, VRChat decides to remove extra avatar favorites from VRC+ (for example by giving 100 slots to everyone), modded extra favorites will likely come back.

Q4: Why remove avatar favorites completely instead of restricting them to VRC+ users?
A4: A fully local mod can't be reliably restricted. Significant codebase drift, however, is at least mildly annoying to deal with, which reduces probability of questionable forks continuing to provide the same functionality.

Q5: Someone is/will be distributing a modified version of this mod with this dumb restriction removed.
A5: See question one. Also, that's not my problem anymore. Also, if it's you who happens to provide that version, make sure your version is easily distinguishable from the mainline one, for example by adding a suffix to the name or version number.

Q6: People who don't want to pay for VRC+ won't pay for it anyway, why even bother? / Answer 2, therefore why even bother?
A6: It's not only about VRC+, but also about sending a message. There's much to be gained from cooperating with VRChat Team. Monetization/cash flow is an important concern for any company. Being pointlessly contrarian here doesn't help anyone.

Q7: This is a blatant VRC+ cash grab! A7: If you choose to look at it that way. VRChat needs to get money from somewhere to pay (likely huge) server costs, and eventually repay investors on top of that. Blatantly and purposefully denying them that is simply an asshole thing to do. Also see question 9.

Q8: Today they come for our extra favorites, tomorrow they'll come for modded feature Y! A8: Perhaps. I can't affect VRChat Team's decisions to paywall certain features.
However, based on the dev stream, it seems unlikely that we'll see much paywalling - there was no mention of "VRC+ only" in respect to any of the new features, except for the few features specifically for other VRC+ features.

Q9: You're a sellout/shill! / MelonLoader devs are sellouts! / Other personal attack or insult! / Other rumor without any proof! A9: I get it, you're 14 and angry. And I have better things to do than needlessly fighting VRChat Team about the direction they want to take their game in and getting a bunch of people banned along the way.

Closing word: With the introduction of VRC+, users and their feedback became much more important, simply because VRChat depends more than ever on user support to continue existing and developing.
You now have the option of voting with your wallet (purchasing/cancelling VRC+ depending on your opinion of the direction VRChat is going in), in addition to talking to your friends about it, providing feedback to VRChat via discord or Canny, and exploring competing social VR platforms.
Capitalism at its best and all that.

Used libraries:

  • LiteDB for all data storage
  • ImageSharp, because unity is bad at loading images from streams on background thread

This mod fixes a set of issues arising from invalid floating point values being accepted from remote users.
It might have a minor impact on performance that scales with player and pickup count. Only use this mod if you frequent publics.

Friends+ Home

Allows changing instance type of your home world to whatever you want.
Setting it to public will choose a random populated public instance if one is available.
UI Expansion Kit 0.2.0 or newer recommended for in-game settings.
Known instance types are Public, FriendOfGuests, FriendsOnly, InvitePlus and InviteOnly (if you wish to edit modprefs.ini by hand)

This mod offers a customized VRIK solver for full body tracking, and a few other IK-related tweaks.

  • No more viewpoint drift in FBT. Instead, your spine bends (up to a limit), or your hip drifts (above the limit).
  • No more weird chest rotations when laying down or upside down
  • No more weird spine/neck stretching
  • Remote players see the new IK too, there's no mismatch between what you and others see
  • Support for universal calibration - calibrate once for all avatars, even ones using different rigs or proportions
  • Support for per-avatar calibration saving (when not using universal calibration)
  • Half-click head follow calibration: hold one trigger to freeze the avatar in place to be able to look at your feet
  • Support for elbow, knee and chest trackers (read below)
  • Optional local NetIK pass to ensure you see the same thing as remote players (not necessary for Index Controller users)
  • Disable FBT even if you have trackers connected, for when you're charging them from your PC

It's recommended to use a normal humanoid rig without any rig hacks (so no neck fix, no FBT fix, no inverted hip, no zero-length spine bones).
It requires at least three trackers (legs and hip). 3-point (no trackers) and 4-point (hip tracker) modes are not affected by the mod.

Canny tickets:

Using additional trackers

You need to enable additional trackers in mod settings before you're able to use them.
To use knee trackers, there are no additional requirements - just calibrate normally.
To use elbow or chest trackers, you'll need to stand straight and T-pose your arms during calibration.
Chest tracker is kinda useless and janky, so don't bother buying a tracker for it.
It's recommended to put elbow/knee trackers as close to the joint they're tracking as possible (but not on the joint itself). For arms, the recommended position is on the outer surface of the lower or upper arm next to the elbow.
If you're using additional trackers, your avatar should generally match your physical proportions - that is, all body parts should line up reasonably well without real height hacks.

Brief settings description

Given that this mod is still work in progress, these are subject to change.

  • Use Pitch-Yaw Shoulders - changes how shoulder angles are computed in 3/4-point tracking. Enabling it usually provides better-looking results
  • Animations mode in FBT - control which part of your body can be controlled by animations when using custom FBT IK
  • Feet stick to ground - uncheck if you want your feet (and the rest of your avatar) to be unable to leave the ground, like in ol' good times
  • Enable IKTweaks (use custom VRIK) - uncheck to go back to default VRC FBT IK. Most mod features won't work.
  • Enforce local NetIK (see what others see) - adds an extra pass similar to NetIK so that you can be certain that you see the smae thing that remote players do. Does nothing for Index Controllers users (VRC does that already)
  • Map toes (use if your feet trackers move with your toes) - if enabled, IK will control your avatar's toes with tracker positions, enabling you to tiptoe. Works best if your trackers actually move with your toes (i.e. are mounted on shoe toes)
  • Use extra trackers - must be enabled to make use of extra trackers. Don't enable options for trackers you don't have.
  • Avatar follows head when calibrating (recommended) - avatars moves with your head when calibrating. This provides better calibration results.
  • Freeze avatar on one trigger hold in follow head mode - if you have previous setting enabled, holding one trigger when calibrating will stop your avatar from following your head. You can use this to align your feet.
  • Use universal calibration (requires follow head mode) - allows you to calibrate once for all avatars. No more standing up to switch avatars!
  • Store calibration per avatar (when not using universal calibration) - if you don't want universal calibration, enable this to save calibration per-avatar.
  • Enforce hip rotation match - if enabled, avatar's hip rotation will exactly match tracker's rotation. Otherwise, IK may rotate the hip to bend the spine more.
  • Shift hip pivot (support inverted hip) - if enabled, the hip will be rotated around the midpoint of two leg bones (where the hip bone should be normally). This greatly improves IK on avatars with the inverted hip rig hack.
  • Pre-straighten spine (improve IK stability) - if enabled, you avatar's spine will be forcefully straightened before solving it. This reduces flippiness/jitter on avatars that have spine bent backwards by default.
  • Straighten neck - this does something cursed to the neck. No further description can be provided.
  • Spine Relax Iterations (max 25) - how much work will be done on bending the spine. Below 5 is not recommended, 10 will provide about 1mm precision for hip positioning, 25 is the maximum sensible value.
  • Maximum bend angles - how much spine/neck can be bent forward/back. If your spine bends too much to your taste or looks cursed on your specific avatar, reduce these angles (minimum recommended value is 1 though)
  • Neck bend priority - neck will bend this much faster than the spine. This is intended to handle the fact that people move their neck way more than their spine, so IK should start off by bending it, not spine.
  • Straight spine angle - withing this angle from perfectly straight, the spine will be considered almost straight and maximum bend angles will be reduced.
  • Straight spine power - controls the curve with which the spine transitions from straight to bend within the straight angle. Recommended values are between 1 and 2.
  • Avatar scaling mode - controls how your avatar scale is computed. "Height" scales the avatar so that your real floor alights with the virtual one (at the cost of you likely getting t-rex arms), "Improved wingspan" attempts to measure avatar arm span more accurately than VRC default.
  • A-pose calibration - use a different calibration pose. In case you don't want to assert too much dominance with a T-pose.
  • Allow more head rotation in 3/4-point tracking - ever tried to look up when close to the ground in 3/4-point tracking? Now you can, even if it breaks your neck.
  • Improved wingspan adjustment factor - your wingspan is adjusted by this factor in "Improved wingspan" scaling mode. If you consistently get avatar arms too long/short, consider tweaking this a tiny bit (to like 1.05 or 1.15)
  • One-handed calibration - pressing one trigger will be enough to calibrate. Holding the trigger slightly pressed will freeze the avatar (if enabled).
  • Don't freeze head/hands inside walls - prevents your hands/head from freezing if your head gets inside a wall.
  • Hand angles/offsets (found in VRChat Settings menu -> left blue panel -> More IKTweaks -> Adjust hand angles/offsets) - you can configure how avatar hands are positioned relative to controllers. Defaults were tuned for Index controllers, but should be applicable to most other controllers too.

Partial source code

This mod includes parts of FinalIK, which is a paid Unity Store asset, therefore source code for those is not provided.
If you want to build the mod yourself, you'll need to do the following:

  • Get a copy of FinalIK from asset store
  • Copy the VRIK solver, VRIK component and TwistRelaxer component into mod sources folder
  • Rename them to match with what the rest of mod source expects, make VRIK_New partial
  • Add the following line to start of RootMotionNew.FinalIK.IKSolverVR.Spine.FABRIKPass : weight = Mathf.Clamp01(weight - pelvisPositionWeight);
  • Remove RootMotionNew.FinalIK.IKSolverVR.Spine.SolvePelvis from the original VRIK solver
  • Rename RootMotionNew.FinalIK.IKSolverVR.Leg.ApplyOffsets to ApplyOffsetsOld, remove override from it
  • Add ApplyBendGoal(); to the second line of RootMotionNew.FinalIK.IKSolverVR.Leg.Solve(bool)
  • Rename Update, FixedUpdate and LateUpdate on VRIK_New by adding _ManualDrive suffix to them and make them internal instead of private
  • Fix compilation if broken


A VRChat mod to notify you when someone joins the instance you're in

Current features:

  • Visual and audible notifications (configurable)
  • Toggleable per instance type (public/friends/private)
  • Can be set to highlight friends or show only friends
  • Custom join/leave sounds - put files named JN-Join.ogg and/or JN-Leave.ogg into UserData folder to override default sounds (they must be in Ogg Vorbis format, naturally)

Lag Free Screenshots

This mod significantly improves screenshot taking performance for handheld camera in VR and F12 key in desktop mode. Benefits are especially noticeable with higher resolution screenshots (4K/8K). Additional features:

  • You can set your screenshots to be saved as JPEG files instead of PNG to save on file size.
  • Automatically rotate screenshots so that proper side faces up (like on your real phone!)
  • Add metadata about world and players to screenshot files (disabled by default; both JPEG and PNG are supported, though PNG metadata is not displayed by Windows - you'll have to use a use different photo viewer software)

Canny tickets:


Headset and display resolutions increase each year, and yet VRChat limits mirror resolution to 2048 pixels per eye. With this mod, that's not the case anymore! Set whatever limit you want, with an option to un-potatoify mirrors that world makers set to potato resolution for their insane reasons. Or you can make all mirrors blurry as a sacrifice to performance gods. It's up to you, really.

Note that increasing mirror texture resolution will increase VRAM usage and lower performance, as your GPU will have to do more work.

If UI Expansion Kit is installed, Settings page in the main menu will get two buttons to optimize and beautify all visible mirrors in the world.


  • Max mirror resolution - the maximum size of eye texture for mirror reflections. 2048 is VRChat default, 4096 is mod default.
  • Force auto resolution - removes mirror resolution limits set by world maker. Off by default.
  • Mirror MSAA - changes MSAA specifically for mirrors. Valid values are 0 (same as main camera), 1, 2, 4 and 8. Lower MSAA may lead to "shimmering" and jaggies, especially in VR.

This mod provides an UI for changing VRChat's built-in dynamic bone and particle limiter settings.
Refer to VRChat docs for particle limiter and for dynamic bone limiter for a detailed description of what these settings do.
Changing these settings should not require game restart.
Requires UI Expansion Kit. Settings are placed into the Mod Settings menu.

This mod is deprecated with the new Quick Menu (UI 1.5). Last revision containing its code can be found here


This mod allows you to reskin your Quick Menu (and, eventually, main menu and other UI elements) using VRChat's new UI Styling system.

Important note: VRChat's UI Style system is currently not released for general use, and, as such, may change at any moment without notice. In practical terms this means that UI styles made for this mod can break on updates easily and frequently.
Custom UI styles (both user-provided and world-provided) are planned for UI 2.5 update. Pray that neither of those will be a VRC+ feature, because you know how that goes.

Styletor will be back next week with new questionable styling facts

Requires UI Expansion Kit

Usage (simple):

  1. Install the mod and UI Expansion Kit
  2. Select "Basic Recolorable Style" in mod settings
  3. Adjust colors as you see fit
  4. To easily replace QM background:
    1. Find an image you want. Ideally it would be a transparent PNG image with 797x1024 resolution. JPEG images are supported too.
      • A more square aspect ratio for the image might be required - that resolution is based on default style, but the actual menu looks way more square than that. Perhaps 1024x1024 would be good?
    2. Put the image into UserData/StyletorStyles, named exactly background_layer_02_lines (including image format extension).
    3. Click "Reload styles from disk" button in mod settings to apply it without restarting.
  5. To install custom styles/skins, put them into UserData/StyletorStyles. Both directory-based skins and ZIP files are supported. "Reload styles from disk" button will show them in UI without restarting.

Creating styles

  • You can export the default style to use as a reference using "Export default VRChat style" button in mod settings
  • Create a new folder in UserData/StyletorStyles, i.e. UserData/StyletorStyles/my-cool-style
  • In that folder, create a file named info.json, i.e. UserData/StyletorStyles/my-cool-style/info.json. This JSON file contains some info about your skin, such as name. See this class for a description of its format.
  • If you want to override style properties, create a file named overrides.vrcss. This file uses the same format as styles in the default skin. No, the format is not documented anywhere, just follow the example of default style.
  • If you want to override images/sprites, place them in same files (and paths) as the default example skin.
  • You can additionally specify certain sprite properties using an extra JSON file named same as image file with added .json extensions, i.e. background.png.json. The format for this JSON is described in this file
  • If you want to make an user-friendly distribution of your style, you can add all contents of your style folder to a ZIP file (so that info.json is in ZIP file root) and distribute that.
  • Note that you should not redistribute original VRChat assets (as provided by default skin export) due to copyright restrictions.
  • If you want your style to support user-provided colors, you can use special color placeholders. A list of them can be found in this file (look for ReplacePlaceholders)
  • You can look at example styles in this folder

Integration for other mods

  • Other (GPL-compatible) mods can provide custom styles via an API
  • Alternatively, mods can have embedded resources with names ending in for mod-provided styles
  • For mods that modify Quick Menu, cloning default elements should be sufficient to make them styled (as long as you don't delete StyleElement component off them)

Known limitations

  • It takes a bit of time to apply QM style after opening it for the first time. This is due to VRChat only initializing styles when the menu is opened for the first time, and the mod having to do a bit of work on top of that.
  • Main menu is not currently recolored. It doesn't use the style system, although I'm looking into applying styles to it too before UI 2.0 update (which would make this menu styleable too).
  • Action menu is not currently recolored. I'll likely add this recoloring as a feature eventually.
  • UI Expansion Kit is not currently recolored. I'm planning to move it to UI style system eventually.
  • New selectors (the "what to apply this style to" part of stylesheet) can't be added currently. Not that it would be useful, but this will likely be supported too, eventually.
  • If you add new properties to a style, changing to another style without those properties will leave them applied to elements.
    • This is why the "Default style fixes" mix-in exists - it adds some properties over the default style to make reverting to it work properly
    • In general, if your skin has issues with reverting to default VRC style, you should also ship a similar "fixes" mix-in style to add missing properties to the default style.
  • UI sounds (or any other resources other than styles and textures/sprites) can't be overridden. This will likely be expanded upon eventually.

Extra credits

  • Non-readable texture export method was adapted from UnityExplorer
  • Lemon image used on the sample lemon QM background comes from Twitter Emoji

True Shader Anticrash

This mod prevents practically all known shader crashes. Note that it can affect how stuff looks as it rewrites shader code to be non-crashy. Setting changes require world rejoin to reload shaders.

Partial source code

Main logic of this mod is located in the native DLL that currently is not opensource. The DLL is build upon HLSLcc and uses Microsoft Detours. An opensource release for it will likely be available at a later point.


This mod significantly speeds up dynamic bones by optimizing collision checks, the simulation code, and optionally providing multithreading.

  • Highly efficient collision checks - hundreds thousands per frame without noticeable performance drop
  • Optimized dynamic-timestep simulation code - no more FPS dropping even more because of DB script doing additional steps per frame
  • An option for multithreading dynamic bone simulation (but this one is of limited usefulness due to simulation being already too fast)
  • No more weird twitching or jerkiness (when using optimized simulation)
  • Collision feedback API for other mods
  • Integrates seamlessly with VRChat's dynamic bone limiter (you may want to increase limits a lot) and global dynamic bone mods

Big thanks to Zettai for finding that collision checks are a very low-hanging easy-to-optimize target, and a lot of other work on multithreading dynamic bones.
Optimized bones have slight visual differences in behavior due to switching to dynamic timestep.
Additionally, some weird configurations might have issues with optimized/multithreaded simulation. Specifically, the following will behave erratically:

  • Zero length bones
  • Dynamic bone colliders on transforms controlled by dynamic bones
  • Dynamic bone components (or roots) on transforms controlled by other dynamic bones

Other mod compatibility

This mod should be compatible with all "global dynamic bones" type mods out of the box.
For mods working on collisions (i.e. ImmersiveTouch), you have two options:

  • Either the mod needs to support collision feedback (see the collision feedback API)
  • Or you can disable custom dynamic bone solver while leaving optimized collision checks enabled - this should be compatible with other mods patching collisions.

    Partial source code

    Main logic of this mod is located in the native DLL, which contains the optimized dynamic bone code.
    Sources to it can't be published due to it being based on the paid Dynamic Bone asset from Asset Store.
    The DLL uses Rust with glam vector math library.

UI Expansion Kit

This mod provides additional UI panels for use by other mods, and a unified mod settings UI.
Some settings (currently boolean ones) can be pinned to quick menu for faster access.
Refer to API for mod integration.
MirrorResolutionUnlimiter has an example of soft dependency on this mod
EmojiPageButtons has an example for delaying button creation until your mod is done

This mod uses Google Noto font, licensed under SIL Open Font License 1.1.

View Point Tweaker

This mod allows you to move view point ("view ball") on avatars. The tweak will affect only you, but other players will see your adjusted head position correctly.
Adjusted view points are saved per avatar.
Requires UI Expansion Kit 0.2.0+. The menu to tweak view point can be found in UI Elements Quick Menu submenu.
Do note that the coordinates displayed in that menu are local offset of the view point, not the coordinates you set in avatar descriptor.


There's a copy of ILRepack.Lib.MSBuild.Task and ILRepack built for netcore/MSBuild 16 shipped with the repo.

IntegrityCheckGenerator and IntegrityCheckWeaver

These two serve to tightly integrate integrity check with mods to make automated patching of it harder. See this writeup for rationale for this.


To install these mods, you will need to install MelonLoader (discord link, see #how-to-install).
Then, you will have to put mod .dll files from releases into the Mods folder of your game directory


To build these, drop required libraries (found in <vrchat instanll dir>/MelonLoader/Managed after melonloader installation, list found in Directory.Build.props) into Libs folder, then use your IDE of choice to build.

  • Libs folder is intended for newest libraries (MelonLoader 0.4.0)
