Focal length & f-stop value in AutoCAD when rendering??

[tzframpton]

Question: I believe that Mental Ray supports f-stop values on the focal depth of a camera in programs like 3DSMax and Maya, but is there such option in just plain vanilla AutoCAD? I'm wanting to have a depth/focus blur on some of my renders with a telephoto lens camera to add realism on some of my outputs. Thanks in advance. :wink:

in 3D max depth of feild is acheived with several rendering passes so it's not a direct process--it's kinda of cool seeing the image build up from sharp to fuzzyness but it's like rendering the same frame a dozen times to get the effect...

 

i think the only way to do this with autocad is to render several images w/ and without the foreground objects and then use a program like photoshop to add the blur to the "background" plate...

That's exactly what I was trying to stay away from. Thanks for the info hazard.
