maxxxmodelz; you could be right, but that's where it gets complicated! In Vue 5 Radiosity settings are represented as lighting models in the atmosphere editor, sampling is a function of the render quality editor.

I've minimised the strangeness here by getting rid of "lighting from sky" in the atmosphere editor. It's still not 100% correct, but good enough that I don't feel inclined to start upping the sampling rate in the renderer too. I think Vue 5 could improve on this, I just don't have the patience. :)
