Hi i tried DOF render, but result is not nice. Blur doesn look realistic. See axle of dray. It looks moore like noise (same look i have in bigger resolution) :-( How can i get nice soft blur? Thanks

REnder a depth pass and use it in the compositor to drive a gaussian blur filter

I have one problem again. Why i have bright areas by Wheels?
They dont have reflection, i have one light source (for shadows) and image based lighting.

The dof looks like that because its sampling function is too low. Basically you have to increase the AA quality settings to compensate.

Prepare for long render times.


The bright areas are caused because you use final gathering. I believe these spots are caused by the specular on the wheels, though I could be wrong. Try playing with the Falloff parameter of the final gathering, to reduce its "range". Expect to get a darker image.
