Hello, I've been working on a mesh for a shark merman tail from The Sims 4 to The Sims 3 but I'm having trouble learning how to assign bones to the mesh properly in Milkshape, Milkshape has always been hard for me and the tutorials for making Sims 3 stuff never helps me enough, is there another way to assign bones or does anybody know of a very detailed or "Dumbed downed" tutorial that shows you step by step way to assign bones in Milkshape, can anybody please help me?!

You can assign meshes automatically with meshtoolit program:
