The usual suspects for trouble in camera transfer between Maya and
Softimage,
depending on the Crosswalk/*.fbx/or else version used:
*Field of View Angle calculation, Horizontal or Vertical? Can also give
grief with 3DSMax.
*Default XSI Picture Ratio vs. Maya Film Aspect Ratio, Softimage
defaults to a 16:9 ratio, Maya to a 3:2.
When I create a Stereo rig in both Maya and XSI 2014, they differ in
Angle of View,
Film Aspect Ratio and a Film Offset in Maya of +/- 0.017 (mm?) vs a
Optical Center Shift of
+/- -0,0043 inch in XSI. Also note the overall 10:1 scene unit related
values...
Enough to make my head hurt by itself already. Which is why I generally
don´t like Stereo much anyway.
I´d check for inch/Millimeter issues in values as well as rounding
errors and Film Aperture woes.
Cheers,

just speculating here...
is there a film shift (tilt shift) or film offset setting in the mix?
that could be off if everything else is spot on
my 2 cents

Hey all,
In an effort to start transitioning over to Maya, *sigh*, we've been
doing look dev on our current project in Softimage 2013 with the
intent to render in Maya. We got approval on the stereo from client
based on our Softimage animation, but now we're having a big
discrepancy between the stereo renders in Softimage and the stereo in
Maya - Maya has a biiig shift in the depth of the renders and it
/looks /like a massive difference in the camera interaxial.
But we're measuring, and all the distances from camera to camera and
camera to subject are exactly the same in Maya as they are in
Softimage, and all the camera settings are the same.
So we opened the scene in Softimage 2015 and exported to Maya from
there, and then they match each other. Great! But here's the thing -
we checked and the renders from Softimage 2015 don't match the
renders from Softimage 2013. So we tried in 2014, and those match the
originals from 2013.
Did something change between 2014 and 2015 in the way Softimage
stereo cameras work?
For the moment we're just trying to eyeball the cameras to try and
get something that matches the approved shot, but something just
isn't making sense. I don't understand how cameras in the same
place in space could yield different results.
Do you guys have any insight?
Thanks!
Andy
