Hmm... you're right that the time channel accessors could be reused across multiple animations, but it's a double edge sword, because if you want to edit one of the animations afterwards, you could inadvertently edit -all animations-
But it's true that glTF is not an editable format, but a final format, so it makes sense to optimize it in that way.
I guess I could add something that, when writing the glTF to disk, to look for equivalent accessors and "squeeze" them.
I could look into it, but I don't know when I'll have time to it; I have some other gltf tasks on queue... so I'll leave this issue open.

That sounds great, or I could help to make a pr.
But as it may affect the current solution, it could be better if you do it alone or we discuss a solution for this and I can then implement the idea. But since I'm not quite familiar with your code, it would take some time and maybe the code style may not correspond.
Here are some general ideas to achieve this:
- As you mentioned, at the writing phase, we loop up the shared inputs and merge them into one array. But this will issue an extra traverse of the structure (or mainly the animation frames of each node relevant to the animation.)
- When we create a curve using
CurveBuilder
, we share the input, like the object pool. This will add some properties to theCurveBuilder
and will need state management. (or define a new class? would be cleaner) But Since your interfaces (likeIConvertibleCurve
) are not supporting this, a solution based on this idea could be difficult / ugly... - Like option 2, we create an object pool and in the
AddPoint
method we check if the new input is corresponding to the inputs in the pool. When writing to the file we check the marker in theCurveBuilder
if there is an input array in the pool and use it as accessor.
There are of course other ideas, maybe you can choose one and then I can help or we can further discuss. (Since I need this function asap, I would like to help, of course)
