I get a very poor Render in cycles. Not just minor problems, but just a cloud of of black and white dots and no contour at all. I read a lot about this now and couldn't get it to work. Does anybody know how to get the settings right. Or better what do I have to pay attention to get better renders. I also tried external renderer like Lux, which increased my CPU usage to 98 % (just the default cube and clicking on Lux and load materials).
Is this normal and what could i do to improve that.
I have various versions of Blender (2.61,2.62,2.63) on Mac OS X.
Thanks for the time.
