[solved] Skeleton and unknown artifact

[TomaszFurca]

HI i have problem with mesh exported by tower of babel. In skeleton animation, when played moving, i see artifact in my player mesh behind head. Rotation, location and scale have zero position.

Yeah, I am looking at problems with skeletons in my own scenes right now.  Please also post your .log file.  Will update as I find more.

Update, I now know what the problem is.  Tower of Babel has switched to packed matrix indexes like a .babylon file.  They are now using the same code on Python side, but there must be something wrong with the unpacking code inserted into the generated code.

Pushed up a fix to exporter.  My meshes with skeletons have no artifacts.  Re-export, check, and mark this '[Solved]' if ok.
