been there, done that. for my purposes its a waste of space. Lux is perfect for architectural visualisation, but sucks at organics( even if you spend an inordinate time tweaking surfaces)

and yes, IC was unchecked, because i always had it set to 0 anyway.

so, for my normal rendering (ie no IC) SR3 IS slower to render a given scene.

i rolled back to SR2, rendered the scene ( with no changes) and it rendered in 20 minutes. the same scene in SR3 was only 50% completed after 5 hrs.

also, on opening PP2012 after roling back to SR2, i had a disturbing 'traceback call'

which mentioned 'RegisterAddOn'??

not sure what to think about that little development..........................
