Hey Guys..

Please take a look at these Images... I mainly want to understand what do the colors in the noise pass mean and when its considered safe to use denoiser in order to have an animation thats noise free and that there are no denoise blotches flicking around...

I would like to know what the green represents.. what the GREYSCALE represents and also what the WHITE pixels represent in the noise pass...

Is it correct to interpret the darker grey to be almost noise free...the green noise free and white pixels/lighter greys where i will have DENOISING BLOTCHING ISSUES?

Hi Nildoe,
yes, it is correct.
Green is noise free, gray almost noised, white is very noisy like firefly, octane will work on it and can makes it green too.
Alternatively denoise tool will remove them.

Hi Nildo,
we set our noise threshold to around 0.05-0.06 to have a faster rendering. 0.03 - 0.04 takes too long to render. Green means it reached the noise threshold you set. White means a lot of noise still left in that area. When it gets darker it means less noise left and it is about to turn green. Also check static noise button.

Thanks Coilbook...

I Appreciate those tips... I never touched the threshold value :). I will try with the values you mention..
