Okey, that's interesting I've never had to do this in Cycles, Vray etc. to achieve desirable results. I'll look into this Another approach would be to remove the sun completely and use the ArchiCAD sun for direct light. I have some HDRIs setup this way I can try!

Hmm, that's interesting. I've thought HDRIs are calibrated to have a big enough range between bright and dark so you wouldn't need to do this manually. Perhaps Cinerender has some special way of using HDRIs which differs from other renderers.. Anyway, thanks for the tip. I'l...

Hi, I have some PG-Skies and they work great in renderers such as Vray or Cycles. With these you don't want to use an extra sun since the HDRI contains a very high amount of brightness in certain areas, which will simulate the sun. So in the best of worlds you should be able...
