Didnā€™t you already create a post few hours ago about this? :slightly_smiling_face: Discord

Yes, I did not provide enough information, I will delete the previous post.

Thanks for the repro steps ā€“ Iā€™ll look into it. Most likely a UnityGltf issue and not Needle Engine specific

Indeed, I checked the code of UnityGLTF, it seems to be missing the code related to clearcoat.
