Question
I have a Terrain for sloped surfaces, and the tiles I want to place (marked in red) are instead being placed with the tiles marked in blue. All tiles onscreen are grass_slope terrain tiles.
For match corners and sides, there’s only 47 neighbor bit combinations used. The combinations you drew on those slopes are invalid and will not be used. You will have to place them manually or remove the tiles you don’t want to use any change the bits on the tiles you do want to use.
