Blending animations with Animator

Hi, is possible to blend the animations with Animator? (For example, I have one character that doesn’t have an animation of walking holding a Rifle, so, I want to blend the idle animation that holds the weapon with the walking animation, how to do it?

You’d have to use an avatar mask, and mask out the arm in the walk. Basically, you create 2 layers in the Animator Controller. 1 layer has all your normal animation, and the 2nd layer has just arm animations. The 2nd layer would have a mask on it to only animate the arm.

I understand, I’ll try, Thank you!
