hello thanks for the reply,.
i will try to explain the issue.
so we have this one character. with a set of animations. and we have so far around 20skins. all of them are extremely similar to original.pretty much what it change is the patterns of the sprites of the skins. i started unlinking the meshes, so i will be able to change the mesh of each skin based on the animation and the patterns.
but still all of them share the same skeleton.
so i noticed that in various animations the mesh keyframes specifically started to disappear in different skins, but not in all of them. so i started thinking maybe its a bug or it has to do about how many different skin meshes can be on the same bones on a specific animation in timeline.
if can send a private message i can show you exactly what is happening.
thanks again for your time time
