So I understand - you created the DOF using the fstop in Maxwell (just like with a real camera) and not using the DOF settings in the SW Camera where you can set the DOF range.To set the depth of field I put the green rectangle of the SW camera where I want to be focused. To change the DOF I adjust the f-stop and the time in Camera setting of Maxwell.
Somewhere in the back of my head I seem to remeber reading that DOF was controlled by the SW camera - but I must be wrong.
Thanks for the info and again - nice rendering.
