If I try to use a custom version of this texture it goes all wonky:-


The texture in the ss isn’t even modified in any way. Is this a known problem?

(This is non-EE).

Looks like UV unwrapping went bad. Some of the OC tiles have really weird UV’s and “just replacing” textures won’t work in those cases. If you use Blender for editing the tile, you might be interested in my tutorial:

I see. Tile editing is probably beyond me, thanks for replying though!
