Playing two montages simultaneously?

Confirmed? lol. You are wrong, it works fine. There are 2 steps: playing the montages and blending the montages. If you stick an AnimNotify on each montage I bet you they both fire which means both montages are playing, you just haven’t blended them correctly. 2 fullbody montages don’t just merge together, if that’s what you want you need to put them into a blend node
