Does the same thing happen without my project? The only difference in my project's caves should be that they are tintable.
I'm not sure
That can happen when you have tile models with packet names that match the names in a different variant. I think the game engine is caching the model components by part name, so if two have the same name it only keeps one of them.
soo... search through my haks and campaign folder to try and find duplicates?
the caves- hall end no door tile has 3 variants, so I mad a test area and put down all three. they look fine in the toolset.
When I check in-game, variant 1 looks like variant 2. Variants 2 & 3 look fine.
