LightCPU performs far better in terms of noise and speed than all other engines, even BiDir, for caustics, direct and indirect light!
It only lacks display of specular bodies and lights which it cannot do by design.
I'd like to see an option for full light tracing in the new hybrid engine where the path tracer only provides those missing parts.
Like PGI light tracing seems to be a gold mine ready to improve all kinds of things with
Disturbing finds:
BiDir looks different (strange dark corners) than Hybrid, that should not be the case given both are unbiased.
PathMetro is not able to get reflective caustics which I think it should do.
looks like something is wrong with pathocl direct light sampling
