I can not have environmental map and volume lighting at the same time? I am doing a scene, where I need to have a environmental texture as the background,and that texture is called an equirectangular map. I also need to have a volume lighting in the world as well. But when I add both the enviromental texture and the volume lighting, and when I render, I get a pure black render, with nothing on it. 

These are my material notes for the world.



Does anybody, know if its possible to have both an environmental map, and volume lighting ? If so, how can I do it ? 

Thank You
The light coming from environment map is infinitely far away, so it get's absorbed by any amount of volume.

Build a sky dome - sphere big enough with inverted normals. Assign and emission shader with environment texture node plugged into it with the hdr.

Set your volumetric environment like you want.

Tadaa! And yes, expect your render times to be infinite, hope you don't have any glass or glossy in the scene.)
