I find light strategy log power and power VS uniform to be in the end of 2 extreme looks.kintuX wrote: ↑Wed May 02, 2018 10:30 am Using Sun & HDRI together changes colors drastically (I assume its sun's color temperature fault, as other 'white' lights work correctly).
Would be nice if suns color was 'over writable' with custom option (yes, Light Groups offer such option, just not intuitive).
Distant (Sun) does fine but produces less caustics
The power and log power with metropolis will overweight all samples from blue sky with yellow sunset sun.
And the uniform only samples blue sky (but maybe with some time it finds sun).
I used as light source this free HDRi maps.
