Re: PhotonGI cache

Yes I did use glossines threshold at 0.0
Probably not a good idea.

Re: PhotonGI cache

Another issue, I started testing pgi on my office scene and I'm seeing a lot of reflections being cut short... I've noticed this happening in every scene. refl_cutoff.jpg Only way to fix this seems to be using very high Usage threshold scale. For example, lookup radius 10cm and usage threshold scale...

Re: PhotonGI cache

So, why does the default normal angle kill so much of the light? 10° seems very low 90deg normal angle: 1min13_90deg.jpg 10deg normal angle: 1min13_10deg.jpg 10degree normal angle kills a lot of GI light and also seems to be darker than pathtracing only.. by the way these are 1min and 13sec renders ...

Re: PhotonGI cache

What is normal angle parameter doing? low values seem to make image darker higher values seem much more closer to normal pathtracing... EDIT: I'm testing this on the 2.1 benchmark scene Also, no matter what I do I cannot make the 2 wall objects gather photons cacheblack.JPG (reseted scale, shading, ...

Re: PhotonGI cache

I'm thinking, shouldn't cache filtering radius get larger as cache entry radius gets smaller?

seems that some recent changes made light leaking worse... nothing helps
I can not add anything more without a test scene.

Re: PhotonGI cache

Oh yes, things are looking much better now.

I did notice though that with some materials I have to raise normal angle quite high ~60 degree, to get gi caching working on them (most likely due to bump mapping)

Re: PhotonGI cache

so apparently, bump mapping is still killing cache for me.

EDIT: I'm actually not sure if it's bump or something else, but I couldn't figure out what is going on... everything is mostly black
