you need to edit the script download notepad++Then go to your project via documents ->New Unity Project or whatever your project's name is->Assets->VRCSDK->Dependencies->VRChat->Editor and open "VRC_SdkControlPanel" or "VRC_SdkControlPanel.cs". Then go to row 871 and replace OnGUIError with OnGUIWarning. Save. Then start unity.exe, go to VRCSDK and click Force Configure Player Settings. Now you can upload. Please dont abuse it.
i made it, i just used some shader that doesnt do anything, and then instead of the sharingan i used a texture of rinnegan. But without the mask would be lit tho. Thanks for this awesome model!
