Hey guys im trying to rig but when i try to do a split it does this, does anyone know how to fix
Hello Matheus. Well Phil and Wayne are the riggers around here, but I'm not sure they could help with a rig just by looking at a screenshot. A lot goes on in a rig, you'd have to inspect bone by bone and follow the logic of what each is doing. Lets see if Wayne answers, he might have so much experience he's at a point where he sees a rig and the rig speaks to him.
And CGCookie has some great Rigging Courses; rewcommended even if you already know something about Rigging. So why don't you put your Subscription to good use, Matheus.
