maya camera to nuke help

[sl0throp]

I am getting my translations from Maya to nuke via a mel script that allows me to export my translate and rotate channels and import than into nuke and all seems to be working okay. The problem that I am having is one of how to translate the horizonatal and vertical aperatures in Maya I have a HD 1080 (1920 x 1080) scene with a camera set to a film aspect ratio of 1.777 which gives me the folowing settings

Camera aperature 1.679 0.945

focal length 35

which gives me a film gate that matches the resolution gate

But in Nuke when I set up a 3d camera and import the data and set my project to 1080 I have a focal length of 35 but my

horizontal aperature is 24.576

vertical aperature 18.672

interchanging these numbers between applications is obviously not working - my camaera match move is perfect but this is driving me crazy - any help would be great.

talk to gary meyer at d2 and ask for the maya chan exporter.
you're a nuke customer so he should be able to get that to you. i think so anyway. i am not a nuke rep but i would certainly hope that they would give support in that fashion

Yes Gary is my contact person and I am getting rotations and translations out of the script but what I am asking is about is my confusion between what Maya calls camera aperture and what Nuke calls camera aperture just because the values between the two are very very different - It seems Nuke is more correct in how you can plug in real numbers here based on filmback or ccd size but the Maya numbers seem to rage more like .9 or 1.25 sorry for the confusion.

i think maya may be in inches?
then just convert the maya numbers (it's prolly .98) to cm and you're good in nuke

Hey thanks for all your help - I have attached a jpeg to explain what I mean - I am sorry I have a thick head and know that you will be able to eluciadte me. I am always in metric in Maya - again thanks - just getting up to speed in NUKE but I really like it.

yeah that's definitely inches
there is no camera aperture that's .9 cm
