So, I tested that new renderer. I really liked it, but damn. no matter how hard i tried, I could not get the render time beneath 12 minutes per frame. and that was without the background. I ended up rendering for 12 hours or so. Rendered on 2 computers, so the overall render time was 22 hours.
soo my conclusion is to drop it for animations. Ive started testing out a somewhat quicker renderer, that gives ok results with less render times. Will try it more later this month. im fine with 10 hours of render with a background, but 22 without a background is too much xD..
