Hi, Unity is PBR ready yet we dont have specular bounce lighting aka caustics. So does this mean that its partial PBR / incorrect lighting since for metals (chrome) albedo is black and hence light bounced from this surface wont contribute in lighting at all. Please correct me if I am wrong here, my aim is to create high…
You probably want to add in some reflection probes for PBR reflections and lighting. I don't think it will do caustics, though. Perhaps you could set up some temporary objects to emit light for the offline bakes, bit disabled in the runtime. There's no easy way to get coloured shadows in like you're after. You could fake…
Accurate caustics are very difficult, and aren't a part of any real-time lighting system I've heard of. PBR really has very little to do with Global Illumination or Caustics; it's more about maintaining accurate interactions between the Albedo, Roughness, and Specular, with the conservation of energy. Faking caustics is…
