As I was not able to get an denoiser render element which is not totally black when rendering with backburner (as described in other posts) I tried the stand alone denoiser tool and got wrong colors. The yellow tones changed to bluish tones. I tried it with or without hardware acceleration and also only with the RGB output, without refllection or shadow elements. What can I do? If somebody knows a way to get a fine denoiser element with backburner it would be far better of couse. Using Vray Next 1.1. With DR all is working fine.
