As other said, you should not share/reuse a material used by a mesh with a Skeleton.
The println is just a way to help you where you share the material, then you could understand why you share this material and avoid the issue in the future.
But, according to the screenshots I’ve posted before, my animated meshes have their own classes with separate material instances. Though maybe the problem is when I, e.g., create an object with an animated mesh (a gun) that I attach to the skeleton control of the mesh of my character because if I launch the app without attaching a gun, it runs ok.
Bonus question: if this wasn’t a problem in 3.0, does that mean animated meshes could use common material instances?
Like previously said, you have the same behavior with 3.0 if you enable Hardward Skinning (I had the same behavior).
Else I can’t debug your data for you.
PS: Sceenshot is not the best to share code. copy/paste in section between triple backquote or gist or github project is far better (see the link Jow to get answer at the top).
Ok, perhaps we can continue this tommorow: I’ve got to go bed.
Ok, maybe you could please take a look at my code and explain where I use the same material instances because I’ve got no idea. If you have any questions about the code, post them.
P.S: the gun classes are very similar.

I think I’ve figured this out: the problem is when I use the following line of code:
someSkeletonControl.getAttachmentNode("").attachChild(someSpatial);
Other than that, there appear to be no other causes of the exception.
