I'm looking for software or a specific workflow to generate terrain tiles for a video game. My plan is to use these tiles with a Wave Function Collapse algorithm for world generation.

I need to generate different tile types with seamless transition. For example, a "mountain" tile should be able to connect to a "hills" tile, which, connects to a "plains" tile, then "shore," and so on. I'd like to generate multiple variations of each tile type that can all connect like puzzle pieces with the appropriate neighbors.

I've tried Gaea and really like its terrain generation capabilities, but I'm struggling to find a workflow that allows me to generate this specific kind of WFC ready tile set.

Does anyone know of any software or a workflow (perhaps in Gaea itself, Houdini, Blender, or World Creator?) that would help me achieve this?
