Auto rock noise generator.
Sculpting rocks by hand can eat up a huge chunk of time so I dove into Houdini’s geometry displacement nodes with noise texture parameters for a quick and good generic rock result.
RGB mask workflow.
Assets that are mainly textured with tilling textures/trimsheets, to add a more unique detail/feel, I create a second UV channel where the baked normals, AO, and RGB mask will be applied in Unreal Engine.
