1.4.1.12 Can I get non-grainy focal blur?

"The focal blur is very grainy. Can I get rid of the graininess?"

Yes. Set variance to 0 (or to a very small value, like for example 1/100000) and choose a high enough blur_samples. The rendering will probably slow down quite a lot, but the result should be very good.
