Great progress. Bookmarked.

For purposes of generative worlds, I have an additional requirement for interchangable equipment and weapons. I.e. a single sword or armor sprite should fit with all humanoid characters, in all animations. I suspect this could be achieved by training against "clipping" tests.

As a start, there should be projections for all four cardinal directions.

Limit the output to palettes of a given size, for classic recolors via GL shaders.
