You can see there are two spotlights under the nose of the big skull and there are lights in each of the yellow cylinders. I can’t mess with the volume distance because I need the fog. I find that’s a crappy way to get out of this problem anyway because you can’t just abandon volumetrics because lights are appearing through solid objects.
edit: I got a better result at 100.00 - but I do have to sacrifice some of the fog bloom that I like. It’s a shame that lights just appear through solid objects. Typical Blender move - keep pushing new features but leave the broken stuff. Volumes are broke on so many levels. I keep filing reports every release.
But to be fair it’s at least tolerable now - thanks for the tip.
