This is just a repo to demo some weirdness with the Babylon.js Blender exporter.
By default, it swaps Y and Z coordinates. If you switch this functionality around in the exporter, it works and renders the models in the same way they were made in Blender, but the textures behave strangely.
I uploaded this repo to demonstrate it for the creator of Babylon.js.
index.html contains all of the logic for the scene. Load it up to see the demo. You will see: a trio of cubes (green = Y axis, red = X axis, blue = Z axis) and two rectangles that have one end smaller than the other. They are both the same Blender model (dummy.blend) but using two different exporters. The one on the left is using the standard exporter, the one on the right is using a modified exporter.
The Babylon directory holds all of the Babylon.js javascript files for Babylon.js version 1.3.2.
dummy.blend is the 3D model used to test the Y/Z flip issue. If you open it in Blender (it was created with Blender 2.68a), you will see that the "nose" of the model points along the Y axis.
io_export_babylon_cyle.py is my modified version of the Babylon.js-Blender exporter, which simply flips the Y and Z coordinates back to what they "should" be. You can install it into Blender as an addon to test it out.
The models directory holds the two versions of the exported dummy.blend file -- the "standard" one that was exported with the regular Babylon.js exporter, and the "cyle" one that was exported with my modified exporter.
