HELP VOLUME TO POLYMESH

i need help executing the "lee Griggs" style volume displacement technique.

this walk through is extremely vague and I'm running into a lot of problems

https://docs.arnoldrenderer.com/display/A5AFMUG/Polymesh+to+Volume

at the volume step it suggest "place an Arnold Volume at the rear of the head and assign the same Standard Volume shader to it. Alternatively, you could use a different mesh and apply the same shader as the head to it. The aim is to have something that looks complex for the displacement texturing process"

so does it mean just a volume mesh like a sphere or a complex one like the entire cloud behind the head should be shaped to get this effect?.

on top of that i am desperate for any help with the node process. the displacement and density node DO NOT directly plug into the output of my range or noise shader but the only tutorial i can find is for c4d and it works no problem....... if anyone has the original lee griggs tutorials up somewhere that would be amazing as most of them now link to a 404 page 😞

The cloud is a .vdb file. I've added a link to vdb files in the tutorial.

Did you open the scene file at the bottom of the page?

I didn’t notice the cloud, I didn’t use the scene file it made a lot more sense knowing the cloud was a separate piece.

The video i was referring to is something I see referenced by people in tutorial threads and even articles. But I guess I’m just assuming the broken links I’m clicking on are videos.

It usual references “under the hood” in the data, my apologies if I’m off base.

What I was really having trouble with were the node arrangements so I was hoping for a more in depth explanation of that somewhere

thank you so much!
