Hy. I have created a skinned mesh with 3ds 2009, and now i would create the animations ,there are some nice tools(opensource or not) for create animations from a rigged 3d model? Thanks

Natural Motion look great, but I'm not a 3D artist myself so I don't know. Most people probably move the bones manually directly in 3ds/maya.

thanks a lot, but if i'm not understand natural motion go in parallel with his engine(and i have arlready a my small engine that i would use) ,naturally if is possible to export in collada the character and animation is the tool that i search.
I don't find his price.
ps if you know another animation program tell to me.
For the existing 3d modeller(3ds,blender,maya ecc..) for you what are the better for animation?

Thanks.
