Okay lol found something in the documentation about the group tool has two modes poly mode and vertix mode and in the setup room your in vertex mode and pose room in poly mode so I switched to the setup room and got his head chopped off lol.

But if there are other ways to do this I like to know. Also I am going to texture M4 so it looks like his head is cut off with blood and parts hanging out lol not sure what I am doing so any suggestion about texturing this effect I am open too.

Thanks :)
