I want to create blurred objects in the background of my picture. I´m using 3ds max and Mental Ray. I can create the effect in depth of field and get the right effect in the scan line-renderer, but when I turn on Mental Ray it doesn't work anymore. When I use the Depth of field (mental Ray) it works, but the blur becomes all noisy. (Filled with small dots of some sort, and I really don't want that!!!) Any suggestions.
