Have been having this issue for a while now and not sure how to get rid of the problem. Basically you see striations in every gradient, particularly bad in areas of extreme contrast. Not sure if its a rendering option, a card issue, or what. No matter what card, amount of memory, or processor I have used over the past, and they are varied, I get the same results no matter what.
Info on PC is an Intel Duel core 2.6 G, 2 gigs of ram, 1.9 T hard drive space. Also have tried a variety of passes and between 2 passes and a 100 absolutely no difference.
Again if anyone can help me I really would appreciate it.
Also side note, when doing alpha layer rendering, I noticed that if there was a light source on an object similar in ways to the one in the attached photo, that it cute out an outline around the object rather than also include the light source and glow. Thats problem number 2. Again if anyone knows the answers to this I would be most grateful.
