Strange DOF defocus artifacts

Hi,

I’m playing with DOF and the Defocus node, but I’m getting some strange artifacts, and I’m really not sure why. It’s probably something simple, but I just feel like I’ve tried all possible settings - I’m really staring myself blind here. Can someone please help me a little? :slight_smile:

Thank you very much!

Vector blur and DOF in Blender suffer the same problem. They generally produce crappy results if you only use one node, especially if you are used to the nicer quality that After Effects produces. And as you have discovered, you can change parameters all day and not get what you want.

There is a nice article on Blender Nation about leveraging DOF.
