Htoa volume rendering beginner question

Hey, I don’t know what I’m doing wrong, but my volumes get rendered as pink squares. I tried it with a simple shelf tool like billowy smoke or bonfire, pipe the out node into a vdbconvert and then setup a volume shader but I can’t get it to work. Any pointers would be helpful!

Pink suggests a missing shader. Can you share your setup (screengrab or scene file)?

These volume tutorials may help your situation.

Hey, thank you for the reply! 

I have figured it out. My mistake was trying to read the volume from a file node that wrote bgeo which I then converted to vdb. Once I directly cached out vdb and then loaded that into an arnold volume directly it worked!
