Those renders are just showing the color difference in the sky. i haven't done any real comparison of the lighting it was just an impression after doing various renders without tone mapping and similar lighting conditions. but materials can be different etc. Just asking, it was less important. my point was on sky colors but i understand if improving this (if is true it could be improved) isn't important.<div><br><div><br><div><div id="ecxSkyDrivePlaceholder"></div>> From: brechtvanlommel@pandora.be<br>> Date: Mon, 4 Mar 2013 13:50:12 +0100<br>> To: bf-cycles@blender.org<br>> Subject: Re: [Bf-cycles] cycles sky texture<br>> <br>> There's various reason these images could be different, using<br>> different sky models, using different tone mapping settings, and<br>> various other settings.
