Can't Get Mesh to Export Properly

If you’re using Blender 2.79, you could also try YABEE; it has its own caveats, but I’ve found it to work well, with Blender 2.78 at least.

(The main caveats that I recall offhand being:

  1. Textures should be applied via materials–just setting them in the UV-editor won’t work
  2. And animations are specified either as start- and end- frames or as actions in the action-editor.
    )

Here’s the main thread for YABEE, which should include a link to a site from which it can be downloaded:
