SDK Bug & Feature Requests

I keep getting this error every time I try to upload an avatar. I already tried disabling my firewall, run it as administrator, disable IPV6, reimport the project and reinstall the whole application multiple times, but nothing seems to fix this error.

i spent the night downloading the client several times and trying to figure out what was happening that made it fail every time. It would not recognize unity being downloaded. i followed the steps using VCC to download everything and it didn't seem to connect to unity's page at all, just errors. i'll keep trying but i was checking to see if others have been having the issue. just in case it might be a bug i wanted to let you know.

I can't read error is what in this text I just know it's for VRCSDK error ↓error code UploadException: Failed to upload file VRC.SDKBase.Editor.Api.VRCApi.UploadFile (System.String filename, System.String fileId, System.String friendlyFileName, System.Action`2[T1,T2] onProgress, System.Threading.CancellationToken cancellationToken) (at ./Packages/com.vrchat.base/Editor/VRCSDK/Dependencies/VRChat/API/VRCApi.cs:958) VRC.SDKBase.Editor.Api.VRCApi.CreateNewAvatar (System.String id, VRC.SDKBase.Editor.Api.VRCAvatar data, System.String pathToBundle, System.String pathToImage, System.Action`2[T1,T2] onProgress, System.Threading.CancellationToken cancellationToken) (at ./Packages/com.vrchat.base/Editor/VRCSDK/Dependencies/VRChat/API/VRCApi.cs:664) VRC.SDK3A.Editor.VRCSdkControlPanelAvatarBuilder.BuildAndUpload (UnityEngine.GameObject target, VRC.SDKBase.Editor.Api.VRCAvatar avatar, System.String thumbnailPath, System.Threading.CancellationToken cancellationToken) (at ./Packages/com.vrchat.avatars/Editor/VRCSDK/SDK3A/VRCSdkControlPanelAvatarBuilder.cs:2524) Rethrow as UploadException: Failed to upload file VRC.SDK3A.Editor.VRCSdkControlPanelAvatarBuilder.BuildAndUpload (UnityEngine.GameObject target, VRC.SDKBase.Editor.Api.VRCAvatar avatar, System.String thumbnailPath, System.Threading.CancellationToken cancellationToken) (at ./Packages/com.vrchat.avatars/Editor/VRCSDK/SDK3A/VRCSdkControlPanelAvatarBuilder.cs:2566) VRC.SDK3A.Editor.VRCSdkControlPanelAvatarBuilder+<>c__DisplayClass104_0.<CreateBuildGUI>b__4 () (at ./Packages/com.vrchat.avatars/Editor/VRCSDK/SDK3A/VRCSdkControlPanelAvatarBuilder.cs:2015) System.Runtime.CompilerServices.AsyncMethodBuilderCore+<>c.<ThrowAsync>b__7_0 (System.Object state) (at <27124aa0e30a41659b903b822b959bc7>:0) UnityEngine.UnitySynchronizationContext+WorkRequest.Invoke () (at <cb81df0c49c643b1a04d9fc6ccca2433>:0) UnityEngine.UnitySynchronizationContext.Exec () (at <cb81df0c49c643b1a04d9fc6ccca2433>:0) UnityEngine.UnitySynchronizationContext.ExecuteTasks () (at <cb81df0c49c643b1a04d9fc6ccca2433>:0)

Hello. My unity keeps crashing whenever the VRC SDK base is added. This is the error: [ Could not allocate memory: System out of memory! Trying to allocate: 1674037094537B with 16 alignment.

I have narrowed down the issue as coming from the XR plugins (openXR, OculusXR, XR plug in manager) that I have failed to remove or disable as unity auto reinstalls them and then crashes immediately when installed. I have confirmed this is the potential source as I ran a blank unity project without the SDK and the installed the XR manager/plugins, causing an instant crash. How do I remedy this or is there an SDK version that does not install or use the XR plugin ins as i don’t test my models in VR within unity itself. Latest VRC SDK as of 7/30/2026

Hello, last month I have updated my avatar project from 2019.4.31f1 to 2022.3.6f1, it was without issues and I did some avatar updates, uploaded and it was fine. Today I opened the project, got an error already while opening and after that I got this error messages in Unity. I get the same error even if I create completely new 2022 avatar project using VRC companion. Old 2019 projects are working, 2022 not. After opening 2022 project, I have only one option in VRC SDK menu "reload SDK" but this button is not doing anything. Is this some issue related to latest updates? I had VRC SDK 3.5.1 and I got this error, so I updated it to 3.5.2 but it's still the same. Can you please check? Thanks

SDK Version: 3.6.0 Unity Version: 2022.3.22f1 Issue: When upgrading my world projects SDK to the newest available one via VCC (and upgrading the unity version as well), my project receives this strange MIssingReferenceException error. This error prevents me from building and uploading my project. I attempted to find the issue in the code, but I could not isolate anything. I've tried to remove the SDK via VCC and reinstall it, but that solution did not work. Previously, I had fixed this issue by downgrading a SDK version, but that solution also no longer applies. Also, this specific error is not visible via the SDK panel, rather the SDK panel lacks any information on what causes it to not let me build. However, I can 'Build and Upload' and it will throw the mentioned error.

Just appeared today, when I was opening the project with VCC normally, and the builder panel is not working, only one specific project appears like this, but with opening other projects for comparison, those other project doesn't appear to have the same problem like this, and I can't really find the reason that cause this specific project to malfunction, I mean like I can just open it last time without any problem, but no more today. Please help. https://gist.github.com/xiaoxi654/966f38b9821b184888708d79764544c2

for EasyEventEditor.cs:262 I had to modify to: if (enableOverride && drawerTypeMap!=null && drawerTypeMap.FieldType!=null) on a fresh install (Version that came with the current VRCSDK). It was constantly throwing a NullObjectException on 264 and breaks the 3D view for editor. I know this is UdonSharp, but it still happened only in the current SDK (Worlds-3.6.1)

For unknown reasons Offline/Local Testing is blocked. The blocking message says "You must fix the errors listed above...", but no errors are listed. And there are no other error or warnings printed to the console. I get the same problem in multiple world scenes across the same unity project. All of them use the provided VRCWorld prefab. Restarting the editor and/or device does not solve the problem. Reasoning: According to the language of the interface, the state listed above should be impossible. Expected Behavior: Offline testing should either not be blocked or list any errors that are causing the block. Failing that the language should either be changed so it doesn't imply a nonexistent reason or a simple catch-all error should be provided. Editor Version: 2022.3.6f1 OS Platform: Windows 10 Home SDK Version: 3.5.2 (box below only accepts an integer)

This does not apply for udon#, and seems to only be an udon graph problem. Reverting project back to 3.5.1 fixes issue.
