ok this is what i found out
from a forum
"try exporting as a maya file from boujou. you can import the .ma file directly into afx. the only problem is that the camera comes in all akward, you need to parent the camera to a null. then on the first frame you set the nulls properties exatcly to that of the camera. then zero out all of the nulls values while the camera is parented to it. this should straighten the camera right out. then you can just delete the null.
if you cant import the file with a .ma, i think theres a plugin on the 2d3 website for older versions.
