Houdini HDA integrates with Unreal Engine to align modular pieces like pipes along a user-defined spline. The method balances procedural automation with the ability to incorporate artist-crafted assets.

Houdini 100% procedurally generated high poly geometry, decimated for low poly, baked and texture in Substance Painter with Mega-Scans. Final renders are in Unreal using a custom shader that height blends grass and dirt based on slope angle. No hand sculpting was used.
