I know and Vue always has been.."Vue is 'Funnie Bunnie'" :) Also the dark arch, ring or circle that you see sometime when doing volumetric stuff facing the camera is cause by the "spread" value...increase the spread value as high as you can go and you don't see it. Any use of Q spotlight or Q pointlight seem to have the light 'source' in front of the object (though its behind)when facing the camers. Just like Vue 3.1, Vue is 'funny' :)
