Loads of LODs

Finally back to doing stuff. Another pile of work went in to doing this thing which should normally be invisible.

In the previous post I showed some automatic LOD generation, which is OK I guess, but doesn't do a great job all the time. For more control, you need to be able to import multiple versions of the same mesh which you have built by hand. The cylinder above is actually three separate objects which were created in Blender and imported from one file. The scales for switching between LODs were assigned automatically (based on the size of the faces in the objects), and are exaggerated here, again, for debugging.

So, that's working. Now just to check it works in concert with some other features, and then I can move on to... other things.
