So I’ve made a running forward animation and a strafing animation(Character is running but lower body is rotated 90 degrees) I’m using these animations in an animator controller. Would it be possible to create a new animation state by combining the two originals so that the character is strafing at a 45 degree angle? I’m trying out blend trees but not having any luck. At this point, it seems my only alternative is to make the desired animation. Anyway, just thought I’d ask. Thanks in advance 
My guess is that to be able to “blend” animations and play multiple animations at the same time, like walking AND waving, you should set up multiple layers within the animator. So you have your basic layer for your feet and legs, and a second layer for your upper body. I haven’t tried this myself yet but I guess you should do some research on animator layers.
