How exactly to use Arnold Denoise in Houdini?

[Andrew_Stanley]

So I follow this:

https://docs.arnoldrenderer.com/display/A5AFHUG/Arnold+Denoiser

and enable the Output Variance AOV toggle

but I always get an error in the arnold_denoiser saying:

"Error rendering child: /out/arnold_denoiser/shell1"

is there a step-by-step on how to use it exactly, in Houdini?

Thank you

All you have to do is put Input and Output names in the Arnold Denoiser.

The Arnold Denoiser will then run the noice executable

That error suggests that the wrong file name is in the Input of the Arnold Denoiser

Here's a video where I use Process Monitor to see what noice command is executed.
