Maxwell for bryce has been discontinued as far as I know. And yes maxwell makes gorgeous renders, but the camera settings take getting used to. You can not avoid DOF effects, its built in the engine and cannot be disabled as far as i know. so you will need to set up your camera view to focus on your object of choise an get your DOF the way you want.
Maxwell renders ultra-slow, glass is absolute horror in maxwell. you thought bryce glass was horror? u aint seen nothin yet.
