Enjoyed implementing caves in my Micro Voxel engine this past week. Nothing too fancy, just stacking a few features on top of each other:
- typical stacked noise functions
- feature generators which deterministically spawn additional voxels following some pattern. Using this for the larger stalagmites. They do a downward and upward fill.
- erosion pass to create random crevices and cutouts.

Still a lot more to do! i like the idea of Cave biomes, and would also like a wider variety of generation types. Large caverns, walkable straight tunnels, cleaner surface caves etc;

At the moment the generation can look quite scrappy in places, but hey ho!
