Rock Maker
The rockMaker smart asset takes in a simple rough mesh as input and fractures and distorts that shape to make rock chunks. UV's are also generated procedurally.
The high poly output includes vertex color in order to bake a chunk id mask.
Simple base rock surface.
The chunk ID is tied to instances of the base rock surface graph in order to prevent noises and cracks to flow between chunks.

-Houdini and Substance Designer procedural asset generation
WIP pipeline for procedurally generated rock forms. Houdini geo and uv's are a tweaked version of Procedural Rock Butte - Houdini Tutorial - Part 01 by Hugo Beyer https://gumroad.com/hugobeyer . The texture is generated by a Substance I made. It is applied and textures are baked for each new rock in Substance Painter. The UE4 material layers on dust depending on normal direction and ambient occlusion.
