I stopped making files and started making systems. One Houdini scene, one switch: floral, stone, dragon. Every product drops into the same room, the same camera, the same light. The only thing that changes is where the switch points. How do you handle variations, one scene or one file per product? https://contra.com/p/cvXglUcM-product-film-retractable-shelving?r=oscar_romero_0l59be1e

One parametric scene wins every time once a client asks for a fourth variant, that's usually the moment a per-product file approach starts costing real hours. Does the switch just swap materials and geometry, or does lighting need any tweaking too when you flip between floral, stone and dragon?
