I have come to the conclusion... no, I won't cancel this WIP, don't you worry tanker fans
But I have come to the conclusion that I will have to focus this WIP on Virtual Sailor, as Blender doesn't seem to "like" the non-simple-mesh thing (having all objects in one file, boat.x).
EDIT: The fix for exporting everything as one DirectX model would be to rotate every object to it's correct axis, accordingly, which of course still works...
EDIT2: I will actually focus on Vehicle Simulator for this WIP... Virtual Sailor fans will have to wait 'til I port it over.
