Trying to change any property in the 3D model material and then Save, it always revert to the imported settings.
If it’s converted from .fbx you have to make sure the materials are “embedded”.
Yes, material with textures.
Even without textures sometime it works, another times it doesn’t.
Tried .glb from blender, sometimes it works, sometimes it doesn’t.
Can you share a video of the issue or the model so I can investigate further?
Sorry, I was with our Develop Account so I deleted the last post.
Here’s the videos.
