PhotonGI cache
Re: PhotonGI cache
so, first gi bounce is still brute force and then cache?
Re: PhotonGI cache
the part I don't understand is "no artifacts but noise that eventually goes away" part, sounds like some progressive solution since even after first bounce you could get cache entries that show up in reflection...
So again, I'm thinking workarounds...

Re: PhotonGI cache
still playing around with settings
Re: PhotonGI cache
Wow, great results!
Re: PhotonGI cache
I like the result.
It seems that you should be able to catch the glossy materials without artifacts.
Interesting.

Re: PhotonGI cache
It is nice indeed, but if you look at the wall light the cache is affecting lighting on the wall next to it, so I guess a little higher usage threshold would be needed in this case

Re: PhotonGI cache
using higher threshold will add more noise in glossy since it will be using more pathtracing calculation as far as i understood. so it's better to play with normal angle and radius
Re: PhotonGI cache
You would need very very small radius to make sure cache won't pickup the light at that place, which would also mean you'd need much more dense cache to get low enough bias, which will lead to long precomp time. Using higher threshold isn't as bad and it is going to make sure you don't get weird light leaks.andreymd87 wrote: ↑Thu Feb 28, 2019 8:51 amusing higher threshold will add more noise in glossy since it will be using more pathtracing calculation as far as i understood. so it's better to play with normal angle and radius
