Hi Kenneth,

The denoiser was able to preserve the ground bump largely thanks to the normal
pass I included. It also helps that the normal and albedo passes can take more
camera blur samples than the final pass, since they are faster to render.

Regarding what it would look like with no obvious focal blur, I'm /guessing/
that the denoiser would smooth out everything under a certain size and color
threshold.

Re: ToVolume. I can't remember which type of proximity technique I used for
that. And I would probably be a bit lost myself, opening up that file after all
these years... that tends to happen with old projects ;)
