Could you create in Prorender, Octane features:
Vectron: Octane Vectron (Vector-Polygon) provides infinite procedurally generated scenes, volumes, and geometry which bypass meshes and volumes. With Vectron you can create procedurally generated scenes entirely on the GPU without using GPU VRAM and with zero memory footprint. You can now render triangle-free geometry using all of Octane’s built in OSL and texture shaders and more.
Spectron Procedural Volumetric Lights: allow you to create procedurally driven volumetric lighting – like spot lights – with blockers, barn doors, gels and more.
