If you mean a seperate animation file.
There is not a seperate file.
The animation is in the character, and then exported as a .x file with the animation baked into it.
So you make youre character then animate it in a 3d program.
And then export the chracter with the animation to a directx file.
In the fpe file you call the animation frames.
each reloaded character has a basic animation. ( walking runnning, shooting, die. etc etc).
There is a program Animer and is almost ready for fpsreloaded.
And is maybe something, you are searching for .
