collisions for a fpscharacter in a cable car animated

hi everybody, my fps character is ejected from my cable car during the lift animation. I mean he can move inside the cable car during the animation imported from 3ds max but, the collision calculations are bad and if I run against the cable car's wall I m ejected from the cablecar... My question is "For a complex animation from 3ds max, what are the options to check in the import menu" Thanks in advance Adrien Jeanneret
