Kryptorock HDA (Mobile Device friendly Rock Generator)
Houdini Digital Asset
Yes, yes, yes, there are Rock Generators out there, and plenty of them.
I'm hoping this is relatively unique, in my tests I can bake down Millions of triangles to under 2,000 polygons and still preserve most of the details using Marmoset Toolbag.
Basically, Hi-res and Lo-res meshes are output, there are controls to alter the look and feel, but the premise here prioritised on high definition detailing.
The timings are not for rendering a single frame, but 120 frames, the mesh has to recalculate to get on the GPU hence why Hi-res is much slower than simple geometry.
YOU DO NEED - To bake the assets from Hi-res to Lo-res using your tool of choice. I could potentially add in the LABS baking to automate the process further (but MT is awesome)!
