When experimenting with lighting setups, I struggle with long long lightmass build times. I’d like to speed this up by temporarily hiding objects. However, neither the “Visible” or “Hidden in Game” flags seem to have any effect on lightmass calcs. Are all hidden static objects really crunched through lightmass?!
Toggling object mobility from Static to Movable I suppose is one way, but this does not strike me as a very nice way of achieving what I want. Is there an ‘exclude from lightmass’ flag somewhere, and can it be easily applied to groups?
