How do subanimations work exactly? The way I'm thinking about them now, I find it strange that you still need at least 1 animation/angle for the "main category" (not allowed to remove).
For example, I want to have an animation called Walking, and 4 sub-animations called Up, Down, Left, Right. Walking is completely described by these 4 sub animations, so I shouldn't have any animation in the main category Walking, but I'm forced to have one.
Also, the events/actions don't care whether an animation is a sub-animation or not, you just need to specify the animation name. So what exactly is the point of sub-animations, and when should I use them?
Thanks.
