WIth what I have learned so far, I have imported an i3d into Blender. I dont have a working importer yet because to import just door.i3d required a hack for the vertex count. The same technique wont work for all assets. This manipulation was just a lucky guess.
The hack is, I needed to take the vertex array from 0x4110 and multiply it by 3 before blender loads it in eg. contextMesh_vertls = contextMesh_vertls * 3
So for example, in door.i3d.
Vertices at 4110

So now there is 24 Vertices and 24UV, which loads correctly, and gives me this
