Dude, your question was so vague and google-able that no one bothered. Blender, so I use, has a pretty solid animating system, and along with Kira's .x exporter, things work fine with making it a FPSC entity. You could try
CharacterFX, it works the same way. Many, many programs can animate models, just search them up. And also, without telling us what 3d modeling program you're using, we can't give you much, I mean, maybe your program can animate by itself, and all you have to do from that point is search up tutorials. BTW, try not to double post, let alone triple post, and bump your threads, you could get banned for doing that.
