Title: ArrayIndexOutOfBoundsException when cloning Object3D from AnimatedGroup
Post by: dcfingerprint on October 26, 2016, 08:01:46 pm: FATAL EXCEPTION in thread: GLThread 248
java.lang.ArrayIndexOutOfBoundsException: length=1640; index=1640

I've seen this exception for a couple of models now when attempting to clone an AnimatedGroup loaded via Bones with reuseMesh = false. (The model was converted from Blender to Ogre to .bones using jmeOgre2Bones.sh.) Not a problem in general but has occurred with specific models from completely different sources. Any ideas? I can send the .bones file if needed. Thanks!

Post by: dcfingerprint on October 26, 2016, 10:23:48 pm: Would it be possible to test by trying with this bones file? It loads and works fine, animates properly, etc. Cloning while re-using mesh works fine (as long as this is done prior to any animation). It is only when attempting to clone (using animatedGroup.clone(false) (not reusing mesh), that the JPCT-AE exception occurs. Exception at same location also occurs with another completely different model.

I am interested in cloning with reuseMesh false so that I can keep one cached in memory (not attached to a World) and then quickly add multiple copies to a world and have them be able to animate independently. If I clone with reusing mesh then subsequent clones are disfigured after animating (probably expected) - however please let me know if there's another way to do this (resetting animation prior to clone doesn't seem to help).

Thanks!
