I'm trying to render some pyro elements for a small project, and right now the only element that I'm trying to render is the fire itself. It looks great in the viewport using Karma XPU, but when I try to render to disk, I'm getting an error message: Invalid volume primitive - missing fields.

How can I determine what's missing and fix this?

Thanks!

Does this happen with KarmaCPU too?

It was. I'm not sure what I did to accomplish it, but I got it working :/
