Split animations and layered animations

Shekill

Hi.

i have two questions :

Is it possible to split an animation during export ( we use Unity)? For exemple creating a complete jump animation with some events (start jump, falling,landing), in order to have 3 clips in Unity.
I heard about tracks for playing differents animations at the same time. But we use Mecanim system, and unity layers does not seems to work (masks are only for "Unity3d" bones) . When playing 2 animations in different mecanim layers all bones are modified by both animations at the same time (not the expected result). Is there a way with mecanim to use tracks?

Thank in advance

Nobody knows? So I guess it's not possible ...

Splitting an animation during export, this was suggested before but hasn't been implemented (yet).
The SkeletonAnimator implementation is mostly for basic uses for people comfortable with Mecanim.
Layers should work but they'll work as override and not additive, which is how Spine works.

Any advanced and specific uses, one could definitely implement the behavior themselves.
But out of the box, no. There's no way for Spine to just act any way the specific runtime wants without programming it first. 🙂

1- Ok i'll try to do it myself with standard event. (is that planned? in a relative short time?)

2- After re-trying it, it works with mecanim layers, but only in override way. It still can be usefull, but a mask for spine bone with weight could be really usefull (for a lot of user I guess).

So I tried to split animations.
I succeeded to split animationClips into smaller animation clips (with an indirect way, using a dummy model and the fbx importer, but anyway). But I cannot play them.

The problem I have now is that Spine does not recognize the animationClip because it's not in the SkeletonData.Animation (Spine type) tab, and so not in the SkeletonAnimator.animationTable. It seems that the only moment something is added in the animation table is during the import (SkeletonBinary.ReadAnimation).
I did not find a way to translate a AnimationClip (Unity type) into a spine animation type (in order to add it in the SkeletonData.animations exposed list). I 'm looking for some kind of 'reverse baking'.

So for now I get this error :

KeyNotFoundException: The given key was not present in the dictionary.
System.Collections.Generic.Dictionary`2[System.Int32,Spine.Animation].get_Item (Int32 key) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:150)
Spine.Unity.SkeletonAnimator.Update () (at Assets/Plugins/Spine/spine-unity/SkeletonAnimator.cs:122)

Does anyone have a solution?

Nobody has any clues?

I don't think coding a whole new "reverse baker" would be a good idea, considering that each time the baking code will change, this could break it.

AnimationClips used by SkeletonAnimator are dummy animator clips. There's nothing to convert from the AnimationClips since they are mostly empty only hold duration and events. All the animation data is still inside the Spine.Animation objects loaded from the json/binary (this is mostly because Unity AnimationClips don't support the necessary flexibility to store Spine's various kinds of animation timelines.)

Editing those AnimationClips will yield unpredictable results.

Ok so if I understand well, the only way to split spine animation would be to change the binary file before it's read in unity (which seems, complicated) or the spine editor exportation system (wich seems even more complicated).
