World/Udon Bugs & Feature Requests

Imposters are amazing, but they can clash with many creative and interesting effects world creators can use within VRC. Projectors and camera effects show them as opaque, or invisible. Often times imposters generate impossibly huge, ruining experiences for everyone in the space when their outside bounds are visible. Please give us the freedom to disable them per-world, or even per-instance. Giving this option to world creators would expand creativity, and would not complicate the end-user experience any further. Alternatively, give imposters their own unity layer so they can be rendered separately.

Allow world creators the ability to moderate their OWN worlds and issue their OWN bans. I'm tired of seeing crashers and exploiters in my worlds and kicking them is nothing. I want the ability to ban certain individuals from my worlds. There is absolutely no harm in doing this. Who is it going to hurt? The exploiters and cheaters. What if world creators abuse it and ban people from THEIR OWN worlds? Well it's their fault their world fails to gather a population. What else will this do? Allow world creators to suit the needs of their wanted audience. it will also help take the stress off of the actually game moderators. Thank you, Lucifer MStar - Creator of 30+ worlds including church of marriages. P.S. Communicate more with your community on what you are doing about these crashers and exploiters and maybe the heat and stress will die down. Honestly this is the most annoying thing communication.

The scientific notation for things like CPU frame time in the performance profiler make it almost impossible to quickly read values from it. Please change things like frametime to be represented in milliseconds as normal floats instead of currently nanoseconds in scientific notation

Calling Camera.Render() on a camera in LateUpdate() or PostLateUpdate() will either crop the sides of or completely erase the contents of the current quick menu tab. When you open the menu the sides will be cropped. If you switch to a different tab the contents there will display normally. If you move to a different tab then close the menu and open it again, the menu will be completely empty. The problem does not occur when called in Update(). Camera component settings do not matter. The problem only occurs in VR. There are a few other reports about avatars breaking when rendering cameras in LateUpdate/PostLateUpdate that have gone unresolved for years, but no mention of the menu breaking. The problem has been present for at least half a year. PC VRChat build: 1801 SDK version: 3.10.2

The ability for worlds to have sub-instances to save on performance at the cost of a loading screen. Basically a portal or Udon function pointing to another world ID that creates a child instance, kinda like a linked list. Moving to a child instance should of course have a prompt to avoid world creators using it as a void dimension for people they dislike. (maybe even add a button to return to the parent instance) Rec Room has had a similar feature for a while, it allows for larger worlds without needing to fit everything in one scene. (especially useful for RAM-limited headsets like Quest)

Players and world creators would appreciate a new character controller for VRChat worlds. It should work mostly like VRChat's current character controller, but has a variety of improvements: Players can stand on moving platforms. Going upstairs and slopes is smoother. Players can get pushed around by the colliders. It's better at getting players unstuck from geometry. Udon has greater control over the character controller. ... And more!

I've been using VRCPhysBones for dynamic elements such as antennas and mud flaps on drivable vehicles since November, 2025 without issues, but some VRChat client update in January 2026 suddenly broke VRCPhysBones attached to vehicles in worlds, causing violent shaking when driving. PhysBones still behave normally in Unity Editor when testing using ClientSim, but when in game, all bones begin to violently shake back and forth, as if fighting against the linear motion of the vehicle. The issue was first discovered in a world that had been fully functional for weeks, when suddenly in January the stuttering began in all versions of the world. The vehicles use Rigidbody and VRCObjectSync at the root and Unity WheelColliders for wheels.

I have been testing EventTiming.PostLateUpdate in SendCustomEventDelayedSeconds and SendCustomEventDelayedFrames, and it is never called. The logs only show those that are using FixedUpdate. (3.10.2) void Start() { SendCustomEventDelayedSeconds(nameof(TestPostLateUpdateS), 1, EventTiming.PostLateUpdate); Debug.Log("SendCustomEventDelayedSeconds called"); SendCustomEventDelayedSeconds(nameof(TestFixedUpdateS), 1, EventTiming.FixedUpdate); Debug.Log("SendCustomEventDelayedSeconds called"); SendCustomEventDelayedFrames(nameof(TestPostLateUpdateF), 1, EventTiming.PostLateUpdate); Debug.Log("SendCustomEventDelayedFrames called"); SendCustomEventDelayedFrames(nameof(TestFixedUpdateF), 1, EventTiming.FixedUpdate); Debug.Log("SendCustomEventDelayedFrames called"); } public void TestPostLateUpdateS() { SendCustomEventDelayedSeconds(nameof(TestPostLateUpdateS), 1, EventTiming.PostLateUpdate); Debug.Log("test called in postlateupdate"); } public void TestFixedUpdateS() { SendCustomEventDelayedSeconds(nameof(TestFixedUpdateS), 1, EventTiming.FixedUpdate); Debug.Log("test called in fixedupdate"); } public void TestPostLateUpdateF() { SendCustomEventDelayedFrames(nameof(TestPostLateUpdateF), 1, EventTiming.PostLateUpdate); Debug.Log("test called in postlateupdate frames"); } public void TestFixedUpdateF() { SendCustomEventDelayedFrames(nameof(TestFixedUpdateF), 1, EventTiming.FixedUpdate); Debug.Log("test called in fixedupdate frames"); }

VRChat is working on an improvement to Udon, VRChat's scripting system. Currently, World creators can write code in two different ways: Udon Graph UdonSharp VRChat is introducing a third way: Soba Creators can write Soba scripts in C#, similar to UdonSharp. Soba scripts are compiled to Microsoft's Common Intermediate Language (CIL). This allows Soba to use a variety of features that are not available in the Udon Graph or UdonSharp.

VRChat finally implemented Steam Audio ! And it's a lot easier to hear other players now.🥳 However, Steam Audio can do a lot more! Here's how Valve describes it on their website: > Go Beyond HRTF > Use fully-featured spatial audio attuned to the physical attributes of your in-game geometry. Combine accurate occlusion, reflection, reverb and HRTF effects for natural sounding immersion. The worlds SDK currently does not yet support Steam Audio, so none of the features above are available in VRChat yet. Please implement Steam Audio into the worlds SDK, or allow users to import it into the worlds SDK.
