A detailed breakdown of a procedural destruction pipeline called PROJECT MAYHEM that bridges Houdini and Unreal Engine 5. The workflow covers Houdini Digital Asset (HDA) cutter logic combining Voronoi and Boolean fracture, custom geometry collection attributes for Chaos system integration, Blueprint-driven weapon interaction, Niagara VFX with Data Channels for performant particle effects, and Dataflow graphs for non-destructive fracture authoring. The pipeline also includes internal material generation using baked thickness, curvature, and AO data packed into RGB masks for visually consistent fracture surfaces.
