Hello, I am War_Major. Recently, I have started using Blender, and I am trying to find a Minecraft rig with good bone structure and is easy to use. If you know of any please let me know and possibly leave a link. Thank you.

UPDATE: I have gotten a good rig now, but for some reason, when I attempt to bend the model's arm diagonally, the elbow movement gets stuck. If some could please help it would be greatly appreciated. Thank you.

Can you screen shot what's going on please. Words don't usually suite this kind of thing 

I hope this helps, sorry if it doesn't

Try selecting everything and doing Ctrl+G( or Alt+G, depending of the OS)

Then try moving it again
