That is also why Bethesda switched from procedural generation for Daggerfall to hand built for Morrowind. I have to wonder if we could train a model now to do this stuff? For terrain it is mostly mappable to an image anyway. Could fix undercut cliffs in a post processing step using voxel models instead. Probably not a very good database to pull from for underground stuff though if you want to generate dungeons.

You're right - I spent a while looking for existing procedural driving games before I started, and seeing how disappointing the Dirt 4 implementation was was all the motive I needed. Thanks for the kind words.
