Thanks Dade for the hard work !I should have finally fixed the darker output of PhotonGI. This is an old test rendering
When can we test this update ?

Mind blowing stuffI assume we are in a pretty good spot if people complain for rendering this in 10mins ... on a i7 2600
Very interesting!Dade wrote: Thu Feb 14, 2019 11:40 am Like I wrote is "mostly" lost because I'm averaging the amount of light reflected by material over the entire hemisphere. This is the average of a constant value for matte, while for glossy is the average of different values. The "shiny" part of gloss is averaged over all the hemisphere (so energy is not lost, it just more "smooth").
If you want to study the problem, you can use indirect cache debug view. If it is not yet clear it is a complete rendering and it should match the output of a normal rendering (splotch-ness aside).
Look this is a rendering with a glossy with 0.0 diffuse and 0.95 specular, PGI rendering:
See how PGI makes the surface look like a diffuse material while the reference is truly glossy. This is the bias introduced in this case however just look at other surfaces, the difference in indirect light is very small (and it is what PGI cache is used for).
Indeed, if all the right wall is black, the bias is huge.
New build with applied fix when whereI will do some testing later with the newest build, thanks for those examples!
It's up... I'm testing it now...Sharlybg wrote: Thu Feb 14, 2019 2:01 pmNew build with applied fix when whereI will do some testing later with the newest build, thanks for those examples!? Need some drugs please

Can i Download now ?I added Russian Roulette to PhotonGI photon tracing, this will reduce the pre-processing time with high max. depth values.
if you want a windows build, then probably in an hour to be safe. It's still testing.Sharlybg wrote: Thu Feb 14, 2019 5:13 pmCan i Download now ?I added Russian Roulette to PhotonGI photon tracing, this will reduce the pre-processing time with high max. depth values.
