While using the new material variant system, I have found a few problems.
First off, it wont allow decals I haven’t uploaded in the same place. If I have uploaded any decals elsewhere they appear white in the game.
Secondly, certain textures appear to be blacklisted. Even if they are not content deleted, work elsewhere as a decal or a texture, they will not work within a material. I have even used a texture in my project for a while, but it suddenly got blacklisted a day after posting it. Even if I try reuploading the file, it still doesn’t appear.
See second problem here, before and after:
^ This was yesterday, around an hour or two after the decal was uploaded. You can see the texture past the door frame.
^ This is what it looks like now.
