You really did a great job in updating Blender integration with Corona.
After trying testing the old chocofur file WITHOUT touching or updating any object to the latest exporter, ie material, maps, texture etc,
it just did work! No crashes and any errors in the Blender console.
Though there are few changes or that are not compatible maybe with the new Corona Standalone that did not render correctly but the exporter is almost backward compatible with what Joel has greatly done and shared with us.
Here is the test.
