VRChat 마이너 갤러리 저장소

Your avatar is using a material (1Dick Txt) that couldn't load properly.

The shader used by this material may be broken or out of date in your project. Ask the creator of this asset what shader and version should be used.

The vanilla shader at Packages/jp.lilxyzw.liltoon/Shader/lts.shader has an internal error:

:660 unrecognized identifier 'CBUFFER_START'

The VRCSDK build was aborted because the VRCSDKPreprocessAvatarCallback 'VrcPreuploadHook' reported a failure.
