Not strictly related, but couldn't find a better place to post it. This video came up in my feed. I think this tool might come in handy for quickly getting real terrain into blender. These are a few thoughts...I've not tested it, but thought I'd share with you anyway. Obviously the mesh would need optimisation for the AC game engine, and I don't know if the scale would be correct on import, and I'm going to make a guess and say that the level of detail would be nowhere near accurate enough for actual track meshes, so I reckon this tool would probably come in most useful for general scene geometry, and perhaps the surrounding landscape. And the UV would need to be converted and optimised, etc, but still!
The video I'd coming from a cgi/image rendering angle, not a game dev angle, so much of it isn't directly relevant to AC. Could probably make some nice specular maps based on the imported UV I'm guessing.
