View Full Version : Mental Ray does not render Lens/FOV of Max camera, help!!!
01-02-2007, 08:48 PM
Am I missing something. I am forced to use MR while I wait for Cebas to get their act together on the 64-bit version of FinalRender.
So I have a scene that I have tried different fov settings. But the render of MR always defaults to 35mm.
Am I supposed to set the lens somewhere else?

Not entirely sure I am understanding the queastion? MR takes
the FOV settings from the Max camera FOV unless you have
set up a camera or lens shader that would alter this behaviour.

Here is a link to a problem file.
Here is a link to an image of what renders for me:
Thanks for any help.

Gotta admit I'm more confused than ever. The file renders
just fine, FOV is adjustable, output is adjustable.
Here is my render with a 20mm Lens with the output
rendered at 480x320. ?????

So you agree with me. I get smae image as you with 20mm lens. But the viewport shows much more in the camera viewport. Does this happen if you create your own fresh MR scene? Anyone else have suggestions?
The camera was scaled, which can cause alot of problems. Select the camera and type $.scale = [1,1,1]
in the maxscript listener field, that should fix it.

Ha, told you I wasn't quite getting the question.:sad:
Well spotted Chris, tis true you never want to scale a
paramentric object because once you do the 'parameter'
controls become essentially useless as they no longer
tell the truth. I set up a fresh camera and the Lens/Fov
setup works perfectly.
Ron, why do you have GI, Caustics and FG turned on
in the scene? With no lights or 'photon' using materials
you are wasting a lot of render time with no gain at the
