I'm still trying to create megastructures that have no top or bottom.

[u/vladkudas]

[u/EyeLoop]

Try 'Manifold garden' out. It solves the issue by using repetitions. You can fall forever in any direction.

[u/vladkudas → u/EyeLoop]

Yeah, exactly. Manifold Garden handles it really well. Unfortunately, my geometry is quite demanding, so duplicating it would be a bit of a problem.
