Hi all,
Not really a bug per se, more of an slight annoyance.
At the moment, skeletons are exported on a per-skin basis,
i have 2 babylon files, each with 2 meshes that use the same bones & animations,
so each file ends up having 2 exact copies of the same skeleton & animations.
So far i've been manually removing the second skeleton and setting the skeletonId for mesh_2 to 0, saving 600-800 KB in each file, which isn't much ofcourse, but it all adds up 
and since the exporter is compiled, i have no clue about fixing it.
Do you think it would it be possible to add a checkbox to the exporter window and then only export unique skeletons once and re-use it if further mesh(es) uses the completely same bones?
Cheers,
aW.
