An is available on this topic!

The previous Voxel Plugin foliage system has been replaced with a integration. This gives full control over scattering behavior, and allows for spawning actors (including voxel brushes) as well as the usual static meshes.

PCG updates from the Voxel World can be paused using the voxel.DisablePCGRegen 1 console command.

With PCG comes the ability to analyze points and do contextual operations on them. This opens the door to things like combining multiple smaller cliff points into a single larger cliff mesh. The logic that would be used for that kind of behavior is generic to any PCG-based system.

example
PCG
A large world with PCG-based procedural foliage, masked by a voxel stamp (writing metadata which is then used to filter in PCG).
