Denioser not updating at end of render

[chris_jackson]

At the end of rendering the denoiser doesn’t update and is still noisy.

The denoiser only updates after pressing the “update” button in the VFB.

max 2025 Vray 7 update 4.

Anyone else experiencing this?

Cloud you please show some of your setting screen shot?

If you’re rendering with GPU, it is expected.

[chris_jackson]

This is with CPU rendering.

Default denoiser settings with .5 opacity

[hermit.crab]

What value are you using for “Post-effects update rate” (Render settings > Settings>System)?

[chris_jackson]

10 which is the default

[hermit.crab]

Okay. Could you send me the scene and a video on how to reproduce the issue?

[chris_jackson]

Hi Aleksander,

Sorry I don’t have time to upload the scene and do a video. Deadline is tomorrow.

I have tried playing with the post effects rate but it doesn’t do anything.

I switched to scanline , then back to vray and now the denoiser works as expected.

[hermit.crab]

Odd. At least you solved it.

[chris_jackson]

Ok not solved.

Same issue just came back.

I will try to save out a scene.

[hermit.crab]

Interesting. Please, do.

I’ve had the same issue on occasion. Found that if you untick one of the lights in Lightmix and turn back on, it reinitialises the Denoise process

Setting with 1.0 opacity will solve the problem.
