VRay Denoiser not working correctly with Light Mix

[DestinHalfmann]

Hi Guys,

I'm having the best time with vray 5.
It's by far the most interesting release in my 10+ year CG career.
Beyond the expected minor issues, it's been a blast working with it so far.

Though, I currently am not able to get the Denoiser working with Light Mixer if I choose a Layer Preset from the drop down menu.
If I load the same layers from the History instead, it works fine.

Basically If I load the Layer Preset, the Denoiser keeps "resetting" the Light Mixer, or at least it shows the Denoised image but without the Light Mix changes.
If I turn off the Denoiser Layer, the image shows the Light Mixer changes.
This does not happen if I load the same layers from the History, or load a Light Mix preset.

I'm using the Intel Denoiser.
Running VRay 5 Update 2.1

I found a Sketchup thread with the same issue, but that was for update 1,5. And there was no new responses.

Has this been logged yet?

EDIT:
Did some further testing, and it issue only appears if I load a Layer Preset from the Dropdown menu, NOT if I load it manually using the load button.

Thanks for the report, the issue is reproducible. I've logged (internal bug-tracker id: VMAX-11733) and informed the developers about the matter. For now, use the manual Layer Preset loading as a workaround.
