How to prevent animation sliding when using layer

Hi there, I put movement animations(walk/run etc.) in layer0 and attacking actions in layer1. When the avatar do attacking, its pose sliding all along. :( I'm not sure if I have to full curved each bone of the avatar or is there someting I was missing? I'be very grateful for your suggestion.

Look into AddMixingTransform function. It allows you to play attack animation on upper-body and walk animation on lower-body.
