SDK Bug & Feature Requests

The PhysBones document ( https://creators.vrchat.com/avatars/avatar-dynamics/physbones/ ) doesn't contain the following information that VRChat 2025.1.3 and SDK 3.8.0 introduced. Execute in deterministic order Maximum dependency depth is 8 ignoreOtherPhysBones option The attached image is a capture of https://creators.vrchat.com/releases/release-3-8-0/

Helps us create beautiful scenes. The first picture is "Shadowmask" (the default and the VRChat currently used). There is a problem with rendering shadows. The terrain has insufficient shadow map resolution, and shadows are not visible. Furthermore, the car is on the border of shadow, but the entire car is dark. The second picture is "Distance Shadowmask." This uses a mix of baked and real-time shadows, and the problem with rendering shadows has been improved. Also, the LightMap is used in the distance, which also improves performance.

In the new SDK 3.7.6, it's now possible to build a world on Linux, but it is not possible to launch a local test with proton. Pls add proton support, similarly to: https://github.com/BefuddledLabs/LinuxVRChatSDKPatch

Summary: VRChat's own VPM packages are getting distributed with missing licence information. A change request for the documentation about VPM License files. According to UPM docs ( https://docs.unity3d.com/Manual/upm-manifestPkg.html ) Licence: > Identifier for an OSS license using the SPDX identifier format, or a string such as “Refer to LICENSE.md file”. > Note: If you omit this property in your package manifest, your package must contain a LICENSE.md file. LicenceUrl: > Custom location for this package’s license information, specified as a URL. For example: > "licensesUrl": " https://example.com/licensing.html " > Note: If the Package Manager can’t reach the URL location (for example, if there is a network issue), it does the following: > - If the package is installed, it opens a file browser displaying the LICENSE.md file in the package cache. > - If the package isn’t installed, the Package Manager displays a warning that offline license information isn’t available. According to VPM docs ( https://vcc.docs.vrchat.com/vpm/packages/ ) > We also highly recommend listing the license of your package in the package manifest. Unity requires this field if you do not have LICENSE file in your project, but we recommend specifying it even if you do have a LICENSE file. This field might be displayed in the VCC interface in the future. The license should use the SPDX format. None of the above is done by VRChat itself. Instead VRChat distributes a licence.txt file inside vpm packages with an URL to the license. Moving (or copying if there is a need for the LICENSE.txt) the licensesUrl from inside Licence.txt to the LicensesUrl key inside package.json seems to be the needed change. VPM (uses LICENSE) and UPM (uses LICENSE.md ) using different license filenames. Is this an oversight? Why did this got changed? Can we have some more clearification about it?

Within a render callback such as OnWillRenderObject, it's useful to be able to check which camera is rendering. Unity has "Camera.current" for this, but it's not exposed to Udon. The new camera API is awesome, but without a property like that, I still can't make my UdonPortals prefab render correctly in the hand-held camera because there's no way to tell which camera is currently triggering OnWillRenderObject. I'd like a property to tell which camera is responsible for the render. A really simple implementation would be a new read-only property like: VRCCameraSettings.CurrentCameraType: An enum consisting of the values "ScreenCamera" or "PhotoCamera". However, I think this API could be extended further to be even more useful. In particular, if a Camera that was created by the world (and so is already accessible to Udon) is rendering, it would be great to be able to access the actual Camera object! Just like Unity's "Camera.current", but only limited to world-created Cameras. An API might look like this: VRCCameraSettings.CurrentCameraType: Enum consisting of the values "ScreenCamera", "PhotoCamera", "WorldCamera", or "Other". "WorldCamera" would be any camera created by the current world, i.e. a Camera that's accessible to Udon. "Other" would be anything else that isn't (yet!) accessible to Udon, e.g. avatar cameras or the screenshot camera. VRCCameraSettings.CurrentCamera: A reference to the current Camera object, just like Unity's Camera.current, except it's only set when CurrentCameraType is "WorldCamera". Otherwise, it's null.

If you have a parameter that is synced as a bool, but in the animator as a float (for use in a blend tree), normally it is cast between types and everything works fine. However if you use the randomize option on the parameter driver for say between 0 and 1, then the value of the bool (because it is a float on the animator side) can be and fractional value between 0 and 1. Compounding this, the casting for bools is not rounded, so any value that is not 0.0 is considered True, so it will almost always become true. This makes it almost impossible to randomize a bool if it is also used in a blend tree. I think this could be fixed if we had an optional checkbox on the randomize mode to only use whole numbers, this should work for bools and ints that are floats.

I would like to be able to import my purchased avatars from the Avatar Marketplace, into my Unity projects after logging into the SDK. That way, I can privately upload any modifications to my purchased avatar, directly to my account.

VRCSDK Version: 3.8.0 If, after build hooks run, the maximum physbone dependency depth is exceeded, the SDK fails the build with a generic "Avatar validation failed" with no further details. It's not currently possible for third-party tools to expose this error, because the detailed error list is passed only to the private VRCSdkControlPanelAvatarBuilder.HandleBuildError (from CheckAvatarForValidationIssues), which proceeds to discard the detailed list of errors. Please provide either a built-in way to display errors that are created as part of postprocessing, or at least an API by which third-party tools can surface these without needing to hook your private APIs with Harmony.

Multi-Platform Build Support Beta Feedback: Problems: When you are done building, you are left in android build mode. I remember there used to be a button to "Switch build target to PC" or "Android". I'm lucky I already knew where to switch the build target, but I know if I were any more new to this, I would've been a bit lost on that. After switching back to PC target, the build and upload button is stuck greyed out. I fixed this by going into the menus and selecting "Clear Multi-Platform Build State". But I am literally doing these two steps for every avatar I upload every time anyway. It would be best if there were a default setting to always automatically switch back to PC build target (or your chosen build target) and clear the build state every time. I need a way to see my avatar performance stats for Android without switching build target completely so I can more quickly find out what I need to optimize.

Title pretty much covers it. No way to make it play based on the time differential
