Combine Animations?

So say I have a walking forward animation, and a sidestep animation. Is there a way to play both at once, like combine the two if my character is walking diagonally? Thanks.

I guess I’ll just make some animations for it, will probably look better anyway.

I think it is not posible

you shuold use AnimationBlend and also animation.layer!
