I combine Houdini with Zbrush in most of my work.
To showcase why this makes sense - despite most studios looking for either a Zbrush or a Houdini artist... - I created this personal project combining 4 environment modeling (Houdini VEX) with a sculpt (Zbrush).
The bush is procedural, created with a space colonisation algorithm combined with volume avoidance.
The ground is procedural, including the animal footsteps.
The rock is procedural, including uv creation.
The grass is procedural (+ super-fast wind animation, not using any particle system!).
All shaders are procedural, custom made.
The horse statue is sculpted in Zbrush (base mesh UVed in Blender)
Animation (space colonisation algorithm implemented in VEX)
