				Quite new to Kray, interested for landscape viz purposes.
A an early WIP -
180 x 240k poly trees
1200x700
1 area light
Kray on 'medium' settings 
28mins per frame.
Any settings I should keep an eye on, specifically for the difference between interiors/exteriors?
Cheers -

				It might actually be faster NOT using irradiance caching.

				There's a check box on the general tab "cache irradiance".
When you turn it off Kray will compute GI for every pixel and the only settings you need to control are FG rays threshold/min/max on the FG tab.
For very fast renders with approximate GI you can use "precomputed filtered" for diffuse model. This will compute only rough GI and therefore save alot of time.

				Thanks jure -
actually it's not there unless you use photon .. something (kray-ing right now, can't check) .. I am playing with more settings, will post some more images soon (but will keep them to this thread, since there is no WIP section and the work on this forum is too good 

 )
