Trouble with Optix denoiser in Render View - HtoA

Hi

The Optix denoiser works for me when I render a complete frame locally - I get an additional denoised frame with the standard beauty. However I can't seem to view any denoised images in Renderview. Checking the logs it does appear to be creating an additional AOV with the denoised filter applied.

[aov] * "RGBA_denoise" of type RGBA filtered by "/out/Explosion5:denoise_optix_filter0" (denoise_optix_filter)

However this AOV isn't available in the dropdown AOV list (Display denoised AOV's is enabled). I've tried adding this as a custom AOV called RGBA_denoise as the docs seem to suggest, and this does yield a "C2" AOV - but there's some very broken buckets and nothing resembling an image at all.

Am I missing something perhaps? Should the Optix denoiser work in the Render View as it does with IPR in Maya? The docs also mention a blend parameter but am unable to find that on the Arnold ROP.

Any help appreciated!

Houdini 16.5.439

Thanks.

Hi Michael,

Currently you can either view the original or the denoised optix AOVs in the image viewer. If Display denoised AOVs is selected, you will see the denoised versions - but with the same name as the original.

We have a ticket to enable both original and denoised at the same time in the viewer.

Cheers

Julian
