I've been wanting to make this update for a while now. The script now supports crystaline fractures! So... there you go. It can automatically break the solid in half along set plane surfaces.
I revisited the crystal script, making it more versatile and easier to use. Here are a few of the types of crystaline solids the script can make. For whatever reason, I especially appreciate the long thin crystals. They grab my imagination.
ProceduralCrystalTest01Four sided crystal cluster
A quick cluster of tetragonal crystals. Note a few small corners clipped off from secondary growth faces.
ProceduralCrystalTest02Septagonal crystals, large group
With scripted generation, it's easy to make crystals which would otherwise never be found in nature. Here is a large clump of seven sided (septagonal) rotationally symmetric crystals.
The whole scene took a few seconds to generate. Very fun to play with.
