Silly replying to myself I know, but I had more thoughts. I'm an architect for 3D worlds and I am desperate, lol, for this kind of tool. I use both blender and grasshopper, but I use midjourney to think and prototype all the time. Obvious but it would be astonishing to have something like this for game worlds. I used another version of this to create "a forest emerging from an aircraft carrier"
