While doing tests about SPPM for another bug report, I have found this bug. After a certain number of passes are done with SPPM, the luminance of the image experiences a sudden shift and and the image becames overexposed. The number of photons to shoot for each pass is a factor, with 5 million photons the shift happens in pass 860 and with 2,5 M photons the shift happens in pass 1720 so it is consistent, once an amount of cumulative photons in the map is reached, something goes wrong. I have attached the scene. Tested in Windows 64bits builds of YafaRay 3.0.2. Grettings.
PD: IRE is disabled in the scene.
