Hi Paolo, naturally I can do it in Atomkraft, but I'm thinking regular Nuke for now.
Tahl, good idea about the Environment light, but I was thinking what Roy did in that same masterclass with the whole spherical harmonics thing. Anybody ever had a look at that and collected it all to a usable gizmo?
