You made a biped... did you rig it? You need to set up a rig in order to get proper controls and rotations. However if you want to do some animation why not use a free rig like the Morpheus rig? http://www.joshburton.com/projects/morpheus.asp
Hello. I was looking at animation videos and finally started to use my 3d max program again but here's the problem, i completely forgot how to use it! I just made a biped but i want to know how to select both items (arms for example), and have the rotate in opposite directions! please help.
