redshift vdb + depth fading.

[Adam Seeley]

Hi folks,

Is there a way to fade off the VDB shader into the distance.

Getting some nice clouds using pre-made VDBs but need some haze for comping.

The pass Volume shader/fog shader doesn't seem to want to play nicely.

Not having much luck.

Thanks,

Adam.

Maybe the depth AOV is usable? (Haven't tried it myself with VDB clouds)

Hi,

I'll double check.. I did try spitting out all AOV's to see what I got and
it just seemed to be Volume_lighting & Volume Tint that showed anything
reasonably useful.

There aren't any handles into the Volume_Material node to help attenuate
anything.

Maybe you can attenuate the density directly in the VDB ICE tree? based on
distance to camera or ray length?

Or create another, intersecting VDB volume of constant density?
