Add Mask to "Denoiser" Layer

[hill_lam]

I like applying Denoiser to walls, but I don't like how it blurs fibre, leather, and things behind glass.
How nice it would be if we can add a mask to the Denoiser layer!

you can take out the beauty pass and the final effectsresult and then use cryptomatte to mask out the visibility of effectsresults pass. so, u can mask out the objects u don't want to denoise.

Ensure the glass shader is set to "Affect all channels" if you plan to denoise what is behind it.
The results will look much better with the option set, than with a mask that won't denoise what is behind the glass.
