VRay VFB bug?

Hi,

I found weird issue in latest VRay 6.2.

I render an image with intel denoise and lens effect, its ok. But then change opacity of denoise to let say 0.5. VFB computing the change but then show me image with denoise 1.0 again. To solve this I have to disable lens effects and after that VFB show proper image with denoise 0.5. Can you fix this please?
Thank you.

Hi, thanks for posting. I am not able to reproduce this on a simple scene. What is the full version of the build you are testing with.

You can find that information here:

If you are using nightly or stable version please install the latest official version of V-Ray and test again.

It happens on Vray for Cinema4d too. I’m using the latest build of 6.2

Hi, this is what I am testing. Am I missing something out?

Hmm, you are right, it is somehow scene related. I tried it on very basic scene with some spheres and it didnt happen. But every complex scene show this problem. I look for some scene and send it to you.

Sound like this one - Calculate sharpen/blur, layer off not doing anything - V-Ray for 3ds Max :: Issues - Chaos Forum
Key is having Lens effects with “Create effectsResult channel” active

Hmm, now, I found out that when I have it active it is not working. Even Sharpen layer not changing when yoiu enable/disable it when lens effects is on. When I disable Create effectsresult channel it works again.
