Hi, A question comes up while using Timeline recently: - say we have a root motion animation that go forward along XZ plane. - say now we want to quickly animate the character going down a slope (adding a Y axis movement). - without extra IK, it appears the easiest approach is to append a parent gameobject to the character, then we can append the Y axis movement. - I understand there exists an animation override track, but it only support masked animation (eg. I can mask the upper body to blend 2 animations), not masking a movement direction. - what we would like to do is: mask all Y axis root motion (in our case there isn't any to begin with) and apply the extra movement via timeline animation. Is it possible via an override track, or is the parent game object approach our only solution? Thx!
