In Maya 2018 sp4 I am seeing skydome lights (as well as background sky shader) disappear when I use attenuation with Volume Atmosphere.
Below I set up a simple test scene with a sky dome light (with hdr image as color) and a foreground spot light. As soon as I increase attenuation value > 0 in the atmosphere volume, the skydome lighting & background disappear. Is this expected behavior?
Attenutation = 0

Thanks in advance for any help with this!
