Vray 3.5 Beta - Denoiser doesn't work in a particular scene

[Alex_M]

I've got a particular scene where the denoiser doesn't work. I can't see it in the VFB (I see only the RGB and Alpha) and clicking on the "Update..." button doesn't do anything either. I'm also seeing some warnings in the log window.

I merged the contents of that scene in a completely new one and I could use the denoiser normally again.

Should I send the scene? Screenshot below.




PS: Another problem is that after I merged the contents from the affected scene in a new one, I didn't get the same exposure of the image. It was darker. Even after I loaded the same vray settings and cc settings from a render saved in history panel, the image was still underexposed compared to the original scene.

Please do send the scene over so we could have a look.

I just sent the scene.

Thank you for sending us the scene.
In the V-Ray messages you will see a warning: The VRayDenoiser doesn't support the current adaptive rendering method and will be ignored.
VRayDenoiser will not work because the scene was saved with the variance based adaptive sampler disabled.
To enable it:
renderers.current.twoLevel_adaptiveMethod=1

Thanks, makes sense.
