As I feared the 1280×720 resolution render took a great deal more time than I wished, as you can see on the comments on the pictures. The main render increased with 54 minutes. Making it render in 1 hour and 11 minutes, which is too much for a turntable that have to be finished before the 6′th of June.
I’m currently trying to reduce the render time by adjusting hairs per clump, plus segments and such. And it seems to work. (Still testing)
There were also an issue with the butterfly’s transparency map in the occlusion and selection pass. But, with a suggestion from a friend we got it fixed.
