I waited for the loot containers to despawn then tried to import but issue was the same. It seems to be the same blocks that have texture issues each time i try it. Very strange indeed. Just a few blocks at ground level. Not a big issue just thought it weird.
I am getting something strange happening when i import an airblock to clear the import area before importing a prefab. A heap of loot containers rain down into the hole. If i don't quit game and restart i get texture issues.
Sorry to be a pain mate. Can i rotate textures? I want a texture to face a specific direction, as in a bowling lane with texture down lane rather than across lane. Is it as simple as rotating the block?
