Howdy Howdy… I need some clarification on that topic.
Can I use the Noise Threshold & the Color Threshold in combination when using the Adaptive DMC ?
VIDEO is here:
like always, thanks for any little help !
For V-Ray 3.20, I would recommend to leave the DMC noise threshold to its default value of 0.005, and only work with the color threshold.
Best regards,
Vlado
thx vlado. but one thing that still is not 100% clear for me. If I use the Noise Threshold value like you recommend with 0.005 .. and let’s say I use the color Threshold with 0.1 … does the color threshold override the noise threshold ? Is the Color threshold dominating or ruling over the noise threshold ?
I am refering again to my short video, that takes just 5 minutes in which I try to lay out this very important questions.
like always… any little help highly appreciated ! thx !!!
The color threshold is for AA samples when V-Ray compares adjacent pixels.
The DMC threshold is for secondary effects, like GI rays, glossy reflection rays, when V-Ray compares the values of the samples computed at a single shading point.
If you look at the graphic here:
the AA threshold is used for the top row of samples (the image samples), while the DMC threshold is used for the bottom row (lights/materials/gi). Does that make sense?

Because dmc threshold is not a simple value of 0-1 quality if you will imho, its a balance from shader/light subdivs. AA is almost like a hard value on top of that.
