How to avoid transparency behind the volumetric world shader?

Question

I have a volumetric shader set up for the World.

But when I render, I see a transparent background behind where the density is too low.

Is there a way to remove transparency and add a background color or texture instead?

Answer 1

Check in "Render Properties > Film" and make sure Transparent is unchecked.

If you want to add a background color, but not have it affect the lighting of the scene you can hookup "Camera Ray" from the Light Path node to a mix shader.
