Could some plz

Could someone plz give me a good tutorial of geo merging becouse i want the peasant using a sword but not that thingy(dont know whats the name of it) in his hand where he cuts wood with .etc

I got an old tutorial on model editing here which maybe helps. At least it learns you some of the basics. You can merge several model edits with each others attaching the models to the attachment points in one of the models.
