Did you rig the character with your own skeleton or did you use the stock Reloaded biped?
If you used your own, you may run into issues. Take a look at Animer, this might be able to help you.
I have not yet modelled a character for Reloaded, mainly because I know it will be a LOT of hassle trying to get them to work.
I wish you the very best of luck with it.
Oh, can you post a screenshot of your character? It's not a requirement of the thread, I just like admiring other artists work.
Cheers
Jay.
