But this is a bug right? Like, not seeing caustics in shallow water or whatever is the issue...
But sds are still not converging anyways, that's another issue right?
I have not been able to make an example where I would obseve any convergence at all no matter how long I render, this looks the same in 200 or 7000 samples: sds stay blurry and dark and only some fireflies appear...
this is how sharp it should look underwater for better comparison this is pathcpu+metropolis with 1000 samples(lacks volume absorption but demonstrates how sharp it should be):
