Hi, I appear to not be able to make a PR for this.
In GLTFUtilityDracoLoader.cs:101, put UNITY_VISIONOS as an extra signifier to set that const variable
#if !UNITY_EDITOR && (UNITY_WEBGL || UNITY_IOS || UNITY_VISIONOS) const string DRACODEC_UNITY_LIB = "__Internal"; #elif UNITY_ANDROID || UNITY_STANDALONE || UNITY_WSA || UNITY_EDITOR || PLATFORM_LUMIN const string DRACODEC_UNITY_LIB = "dracodec_unity"; #endif
