Does UE5 actually support caustics outside of the path tracer, in the sense of diffuse-specular-diffuse lighting? The only branch of UE that I’ve found support for real-time caustics is NVRTX, which is way more of a hassle than it’s worth. I’m just curious, the only features Lumen is really missing at this point is support for light transmission and caustics, and after that I think it can pretty much supercede the path tracer in every area except sheer quality.
