If I'm not mistaken, you're converting from SA to VC, yes? In that case, the rigging is way different between the games. They aren't backwards compatible that easily. You'll have to figure out the dummies and rigging before you can export it. I'll be honest, peds aren't my thing so I couldn't tell you how.
