I am guessing that the camera appears to be at 0,0,0. If this is the case,
then I think the problem is that by setting custom camera text you override
the camera's tranformation matrix (if this is how it's called).
The full camera text should be:
-- ---- --
camera "perspShape"
output "+rgba" "iff" "mentalRayOutputChannelTest_v01_01.iff"
resolution 320 240
aspect 1.33333
aperture 1.41732
frame 1 1.
clip 0.1 1000.
focal 1.37795
lens "maya_state" (
"passAlphaThrough" off
)
end camera
instance "perspShape_inst" "perspShape"
tranform 1 0 0 0
0 1 0 0
0 0 1 0
tx ty tz 1
end instance
-- ---- --
where tx: translate X
ty: translate Y
tz: translate Z
For rotation, I am not sure how the matrix should be. I only know how the
equivalent opengl matrix is composed and I can tell you that it's kind of
ugly.
You could though see how Maya exports the camera (without custom text) to an
mi file and copy the instance block in your custom camera text.
Maybe there is an easier way (try the mental ray forum) or maybe I need some
sleep.
Hope it helps,
D.
