VRay VFB denoising and lightmix problem

[Jiri.Matys]

Hi,

I had this problem in VRay 6 and now I have it in VRay 7 too.

When I use denoising with lightmix feature together and I set some light intensity different from its default in lightmix, after denoising image looks like I didnt change anything in lightmix. It denoise the image but show the original image without lightmix changes. So it is completely useless and very annoying.

Can't seem to reproduce it. Mind if you attach a simple scene and some screencaps of the issue?

Yes, happen pretty randomly but when it happen nothing help. So I have to change settings, reset lightmix and rerender.

I've had this problem too a couple of months ago with V-Ray 6. I just gave up and didn't use LightMix. It was a small interior scene. Nothing complex or convoluted as a setup. As @Jiri.Matys said, it was pretty random and couldn't reproduce it every time.

Yes. I think it happen more when I work on a scene for a longer time.
