SDK Bug & Feature Requests

This occurs when the game object the constraint is attached to (or a parent of it) is enabled, looks like a missing null check. I'm almost certain this didn't happen prior to world dynamics. MissingReferenceException: The object of type 'VRCPhysBone' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object.

The error "You must provide a path to the thumbnail image when creating a new avatar" which is intended for new avatar uploads blocks updates to existing blueprints if the build is started before the thumbnail is (down)loaded. Repro: Have an existing avatar project, with the SDK panel hidden (closed or docked but tabbed away) Open a new session of Unity for the project (thumbnail not cached) Open/switch to the SDK panel and immediately hit "Build" In theory between 2 and 3 you'd have made changes to the avatar and then decided to upload, which is exactly when I encountered this, after thorough testing in Unity I decided to upload to test in VR, but it was the first time I tabbed into the SDK this session. Likely affects most/all SDK versions with the newer build panel.

Since 3.10 came out the option for "mobile multiply/additive" are broken!! across all SDK versions!! They work in unity and the sdk allows us to select them, but they break in game! I AM aware "vrc does not support transparency on quest" yet myself and MANY other creators have been using these shaders for at least over a year and have had NO issues until now!! I ask that you please look into this as MANY of us cannot create for quest until you fix it! : /

When I try to use "Build & Test" with a number of clients above 1, one of the windows works fine, but all the others just sit on a black screen and won't even let me close them without doing End Task in the task manager. I also actually tried manually launching two instances myself, using the --profile=1 argument for the second one, and encountered the same problem, so this might not be specific to Build & Test.

For whatever reason, .enabled has not been exposed to Udon for ContactSender and ContactReceiver directly, but can be done so via animations. This seems like an oversight to me. SDK version is Worlds 3.10.1

UdonSharp reports Utilities.ShuffleArray (the T type) as not exposed to Udon, despite it working just fine in an UdonGraph program. The int[] version of this function does compile in UdonSharp.

Followed the this https://creators.vrchat.com/platforms/android/build-test-mobile/ but it fails to lunch vrchat on my phone after building it even puts the file on my phone so i know for sure adb is working and getting this in my editors console and tried this with 2 different world projects now AdbException: ADB failed with exit code 1.

This is important for Asset searching. By default, Unity hides any and all assets that are located inside Packages. In order to make sure searching for Assets from areas such as Inspector fields to show items located inside the SDK by default (such as Menu Icons, Prefabs, etc.), the following line must be added to the package.json: "hideInEditor": "false" This will ensure this button (see screenshot) doesn't need to be toggled to find example assets in the SDK.

When we uploaded multiple avatars in a row relatively quickly, we encountered an issue where the upload process would freeze without any error message shown on the console or in the log files. This issue comes from two main causes: Firstly, the VRChat SDK silently ignores exceptions that occur in VRC_SdkBuilder.RunExportAvatarBlueprint . The catch clauses has comment // Errors are handled by the error callback , but most of the exceptions do not initiate error callback, including this one. Secondly, the VRChat SDK does not handle the exception occurred when trying to delete the last uploaded .vrca file. Removing the last uploaded .vrca file is not a critical step in the upload process, so it should not cause upload to freeze. However, currently, if the deletion fails, the upload process will not continue, leading to a freeze. When we replaced catch clauses to catch (Exception e) { Debug.LogError(e); } , we were able to see the following error message in the console: System.IO.IOException: The process cannot access the file 'C:\Users\****\AppData\Local\Temp\****\****\637e8e6c-8eb6-4cd2-a651-241fb7aa6ed3.vrca' because it is being used by another process. at System.IO.FileSystem.DeleteFile (System.String fullPath) [0x0001a] in <27124aa0e30a41659b903b822b959bc7>:0 at System.IO.File.Delete (System.String path) [0x00014] in <27124aa0e30a41659b903b822b959bc7>:0 at VRC.SDK3.Builder.VRCAvatarBuilder.ExportCurrentAvatarResource (UnityEngine.Object avatarResource, System.Boolean testAsset, System.Boolean buildAssetBundle, System.String& avatarPrefabPath, System.Action`1[T] onProgress, System.Action`1[T] onContentProcessed) [0x003bc] in <81261fc1c1e94d15bda5671000ac0e16>:0 at VRC.SDK3.Builder.VRCAvatarBuilder.ExportAvatarBlueprint (UnityEngine.GameObject externalReference) [0x00021] in <81261fc1c1e94d15bda5671000ac0e16>:0 at VRC.SDK3A.Editor.VRCSdkControlPanelAvatarBuilder.Build (UnityEngine.GameObject target, System.Boolean testAvatar) [0x0040b] in .\Packages\com.vrchat.avatars\Editor\VRCSDK\SDK3A\VRCSdkControlPanelAvatarBuilder.cs:2600 UnityEngine.StackTraceUtility:ExtractStackTrace () UnityEngine.DebugLogHandler:LogFormat (UnityEngine.LogType,UnityEngine.Object,string,object[]) UnityEngine.Logger:Log (UnityEngine.LogType,object) UnityEngine.Debug:LogError (object) VRC.SDK3A.Editor.VRCSdkControlPanelAvatarBuilder/<Build>d__132:MoveNext () (at ./Packages/com.vrchat.avatars/Editor/VRCSDK/SDK3A/VRCSdkControlPanelAvatarBuilder.cs:2605) System.Runtime.CompilerServices.AsyncMethodBuilderCore/MoveNextRunner:InvokeMoveNext (object) System.Threading.ExecutionContext:RunInternal (System.Threading.ExecutionContext,System.Threading.ContextCallback,object,bool) System.Threading.ExecutionContext:Run (System.Threading.ExecutionContext,System.Threading.ContextCallback,object,bool) System.Runtime.CompilerServices.AsyncMethodBuilderCore/MoveNextRunner:Run () System.Threading.Tasks.SynchronizationContextAwaitTaskContinuation/<>c:<.cctor>b__7_0 (object) UnityEngine.UnitySynchronizationContext/WorkRequest:Invoke () UnityEngine.UnitySynchronizationContext:Exec () UnityEngine.UnitySynchronizationContext:ExecuteTasks () When we disabled the real-time protection of the antivirus software for the temporary folder, the upload process worked as expected without freezing. Therefore, we conclude that the issue is related to antivirus software holding a handle on the last uploaded .vrca file, which prevents it from being deleted.

as seen in GIF below, alerts are jittering between two text layout states in which the newlines are placed differently, causing the whole layout to jitter. (side note: the 16k texture is a dev reference image! I'm not stupid enough to include that in the final release ;-; don't worry guys)
