To anyone using this, does this work yet?
Which version of Blender do I have to use?
Is this the only / most recent Blender exporter available?
I think this is the only one Orbiter mesh plugin for modern Blender.
I haven't updated the plugin for a long time,but it should work with the latest Blender versions. Blender API is stable, and Blender developers usually don't change it.
