don’t know why I didn’t figure this out before, but instead of JUST using adaptive AA -4/-4 when you are creating an irradmap for latter use, also use render region and render just a few pixels, little bit quicker. 
mmmmm…Good tip 
Cant you also render it at half or quater size, and then have the iradiance map max at 1 or 2?
I havent tried it, but i cant see why it wouldnt work.
yeah, just up the min/max rate & up the Hsph subdivs
[*edit* woops]
I’m somewhat new to VRAY (I bet you’ve heard that statement a lot), and I was wondering if you could possibly explain to me why / how you can render an irradence map seperately? I always that when you turn on GI, the irradiance map is rendered in prepasses before actually rendering the image? Am I incorrect? Any advice would be welecomed.
Erhh.. why not just use the “Don’t render final image (only compute GI maps)” feature, then NOTHING gets rendered.

…some of us are just too old school to use such new fangled gimmickry
