I'm working on the Cave Generator tool for this challenge. The idea is that it is going to be used for isometric RPG games.
The tool will work with primitives as an input(I'm still thinking about using a curve as an input). Then the input will be used to drive modular wall and rocks(the ones that will lay at the bottom of the wall) points, ground shape, and additional rock/cliff structures(columns in the middle).
The list of planned features:
Expose parameters to customize the default assets Modular walls Geo input for custom rocks Geo input for additional rock/cliff structures
If there is time left, I will probably add more features.
Got some time to work on the asset. Made it match its shape to a 1x1 grid so that rescale works without a hitch. Generated default rocks, changed ground generation process, and added walls. Though, I need to change them to planes instead of boxes.
