Just Firefly render tests, that's all.😊💖🥰 Testing some Firefly volumetric shaders I made; using my own custom render settings. I assume Firefly was doing quite well but modern GPUs architecture pushed further modern functions support to the newer generations of rendering engines. Renderman with it's later builds supports GPU and CPU as well but they are big guys with huge resources and their APIs are obviously proprietary and for sure, it's hard to chew stuff, to only use an euphemism. Superfly is actually a huge monster, and it's capable to compete the most expensive render engines. I'm very happy we have the Superfly warp engine. No postwork, never ever.
