Who can tell me how to finish my model....

Thank you oinkerwinkle i've got your model tools.

I want to make a model from MK(MountainKing): a barbarian with a blade at right hand and a whirlwind animation. So i need MK's body + BladeMaster's Blade + Blademaster's Animation.

At first i use Vertex Modifier to delete MK's weapons.
Then i use Animation Transfer to give MK blademaster's animations.
The 3rd step should be add BM's Blade to MK. But i dont know how to do this.
Because MK's weapons are in the same geoset with his body. But Blademaster's blade is in a separate geoset. I tried many times but failed.

who can tell me how to do? or tell me another way to edit this model?

I think maybe i can replace BM's body with MK's, but i dont know how to do ...

I've read the tutorials but have no idea yet. Thanks....

It sounds like you're looking for geoset merging. There's a tutorial and program for that on the tool site. You can get the general idea from that and then apply it to your sword problem.
