my workflow is usually

set up nulls in maya that define the scene

parent them in groups with a dummie camera at the bottome of the chain (the nuls can be animated too)

bake all animations out in maya to make sure there is no interpalation

import into ae

unparent all my nulls
scale them to like .01 or something (so i can see them all better
then if there where any moving nulls with things parented to them (like if i had a moving box and i had 1 null animated and 3 other parented to it) reparent those

then create another null and move it to the orgigin (0,0,0)
then reparent everything to that(unless it is parented to a moving null) and scale it up till the scene is the size you want
everytyhing will remain looking acruate in your camera

make sure you remeber what you scaled that null to so if you have a change in your camera move you can just bring over the camera again and scale it to match


some times you have to tweek the focal length in after fx
so it is good to have the nulls that are defining like courners and stuff cause you just tweek the focal tell they all line up with the rendered geomatry

Hello,

I've imported a camera from maya in after FX 6.0, (baked) . and I had to adjust the zoom value in the afterFX imported camera becouse of this focal length difference.
why? should'nt work exactly as the maya camera?

thank you !!

hey

i don't konw why sometimes it breaks

i asume it has to do with how in maya you can screw with things that you cant in ae like horizontal and verticle app independetly and stuff like that


generally i always use a camera that is set to 35 mm full apature
that will always come in corectly

when i start playing with strange camera settings those some times focal lenght breaks and sometimes it breaks alltogether

so use something consitent that works for sure


if it is off you could test it by making a new camera parent constrain it to your old one set teh new one to 35 mm full apature and ajust the focal length on that in maya till it matches
then bake it and export it and see if it lines up perfect in ae or not ?
