Artist Oscar Gaya published procedural Houdini Digital Assets for highways, pipes, gears and rope bridges, including workflows shown with Unreal Engine.

Highway and pipe generators

The highway HDA accepted a curve and exposed road size, scale and spacing for edges, planks and streetlights.

The pipe generator also followed a curve, with controls for radius, dividers, screws and UV seams.

Gears and rope bridges

The gear tool combined base shapes, bevels, discs, detail arrays and screws through intersection, subtraction and union operations. A separate HDA generated rope bridges.

Artists should inspect asset licences, Houdini versions, UVs and Unreal cooking before production use.
