I mention this in the WIP thread of the “Kong” project, but haven’t received any insights.
I am using a panoramic HDR image as the principal direct lighting source for my scene at the top of the Empire State Building, as well as the visible background. To increase the sense of space in the scene I wanted to add some Atmospheric Perspective (aka haze) by using Volume Scatter at a low Density value. However, I found that doing so completely negates my Environmental Lighting, and incidentally also kills the Sun lamp I use to sharpen up the cast shadows. I’ve used Volume Scatter before but with a mesh light as the main source – tests show that this seems to be the only usable method of lighting within a Volume Scatter volume, but a mesh light doesn’t even begin to match the lighting scheme I’ve already designed.
Am I missing some setting or adjustment to allow the desired lighting plan to work properly? I tried many reconfigurations of the scene to no avail. Is there another method of introducing haze for Cycles? I’d rather avoid compositing or use of Mist, which I find looks very artificial.
