I'll be happy to make my stuff available to you, Jero. What's the best way? Should I private message you a download link when I get around to uploading?
Note that in a couple cases I eliminated LOD_1 wholesale, to save on my workload due to doing this 'manually' with Excel and Notepad. (It takes several hours to fix LOD_0, and while simpler and generally similar to LOD_0, LOD_1 would still take a couple hours, probably.)
The result is an extension of the view range for LOD_0, which unfortunately usually results in flicker on the hangar floor seen through the doorway at longer distances. This is because of its necessarily very small height above the underlying ground. An LOD made for longer view distances has the floor either eliminated or raised rather higher so as to not flicker.
My main concern is this floor flicker, which is best handled by reinstating LOD_1. After seeing which surfaces I've added and/or corrected in LOD_0, you should, I hope, be able to carry over (where necessary) to LOD_1 without too much difficulty.
