I have two animations, one is a hit reaction animation, which is a light shake animation. And I have an attack animation. When the enemy attacks, play the attack animation montage, and even if the enemy gets attacked by the player, it will play the shake animation but not interrupt the attack animation. So the result should look like the enemy is attacking and also shaking at the same time. So I guess this is not like a blending issue, is more like adding the relative animation data to another animation data. So how can I reach this?
