Hi SasMaster
Fpsc is a game engine that you can use to create games at ease,its a point and click tool.
All the model packs are in .x files so you can use them in almost any aplication but 3ds max unless you your self can convert them into max.So all I am saying is no, none of the models are in fbx format.
With all that being said, You can still get the said model then rig it and animate it your self in 3ds max. What I do Is I use MilkShape 3D 1.8.5 to open the .x files then I export them out to .obj then I open them in 3ds max to edit,or I just make my own.
my signature keeps being erased by a mod So this is my new signature.
