Cant render a volume without the background?

Hello!

My question is relativly simple.
I created some sort of cool thing with a volume shader on a sphere, and a displacement map (fractal) on it. It renders fine when there is a background (either the sky or a plane). But right when I hide the sky background making the background transparent, the effect of the displacement map dissapears. (see images)

(i didnt make it to the end of the render, its way too long, so you have just the pixels, good enough to see whats going on)
Maya 2018 with Arnold.

Thanks a lot !

Is this the sky shader or the skydome light? I did a test with the sky and it seemed to work ok. Have you tried it with the skydome light instead (you can adjust its Camera Visibility). Can you share a simplified scene?
