Nope, I made this choice long time ago.
What do you mean funky textures? Need a screenshot. Also check vanilla LOD first that it is ok there, then locate corresponding _lod.nif file and check it too.

yep that was a bad bug report! I know better but I really just wanted to ask if I needed to re-run the process. I will test in vanilla and get some screens but it is like the coulombs that hold up the track are turned 90 degrees in the LOD. They look blocky in the distance.

TTW with LODGen added

Vanilla FO3 with no LOD Gen.
I'm using Wasteland 3,7 as a reference but it seems to be all the monorail tracks in DC.
Hope that's more helpful!
The monorail tracks in NV do the same thing. I'm running around taking screenshots all over, I'm regenerating the LOD now with the missed files to see what changes.

Here I updated the pack with most of the missing normals.
The following files however do not exist at all in any form.
textures\nvdlc02\landscape\trees\nvdlc02_redcedarneedlesev_lod_n.dds

Thanks for reports, but majority of your reports are not bugs really, but rather bad quality vanilla LOD models/textures or an absence of them.
If you think you found a bug, then first save, go to LOD meshes folder for worldspace and rename "blocks" folder to "_blocks" for example so the game will switch to vanilla files, load back and confirm that there is indeed a difference between newly generated LOD and the vanilla one.
Once confirmed, please check the source _lod.nif mesh is present for that object, have existing textures and look normal in NifScope. If you don't know how to get a model name for some object in game, use this guide

Please use nifscope 2 http://afkmods.iguanadons.net/index.php?/topic/4136-nifskope-20-dev/ it can read textures from BSA archives if you add them in options, makes it much more easier to check lod models.
I don't see anything wrong with monorail http://i.imgur.com/kev8tmo.jpg and here http://i.imgur.com/A217SOX.jpg and many other posted cases, it is just a bad quality LOD meshes/textures for me.
However the missing fort walls and pink rocks are valid bugs. Check their _lod.nif meshes as I said, I'm very interested in the pink ones. Try to also open generated lod mesh in NifScope for that cell.
Let's concentrate on New Vegas worldspaces for now as I don't have TTW and my FO3 installation is collecting dust for 5 years and doesn't even load, need to reinstall it.
I already have billboards for trees, but due to a game bug they can only be reasonably used for small objects like bushes in my opinion. Other bigger trees should be redone as objects lod. New lod meshes, improved ones, higher resolution lod textures or texture packs variations can be done, but this is a manual modeling/texturing work. I'm leaving this up to proficient modders.
If you want to create a new lod model, name is as full mesh but with _lod.nif suffix. If you want to replace lod textures, name them as textures used in corresponding _lod.nif model, or edit those models in NifScope and change textures there (though this is unreasonable unless model itself has changed).
Regarding normal maps "The following files however do not exist at all in any form.", they must exist but with a different name. Locate their _lod mesh, check normal maps file and rename as diffuse one with added _n suffix.
By the way, this is vanilla monorail LOD

It looks exactly like on your screenshot. That's why I'm asking to check _lod meshes first before reporting. Vanilla LOD is so bad in quality that it looks "bugged" sometimes.
I'll check the LOD meshes tomorrow for the ones which I couldn't find, I planned to do that any way but I already spent half of my day testing and had to go do some other work.
I posted both plusses and minuses that I saw/see. I also posted a couple "would be cool if" things, thought I made those pretty clear ;). If you only want bug reports I can do that.
The Gomorrah sign is also clearly a bug, I did check the normal there and there is nothing wrong with it. Something to note that I can't put in a screenshot is that the flames seem to move outside the sign as you move away from it. That's pretty strange and no idea what can make that happen.
Here are some shots with vanilla LOD (only lod texture changed) to demonstrate the bugs with the rocks, around goodsprings and ivanpah, as well as the monorail.
Do note that the distant LOD of Vegas is better with FNVLODGen by a visible amount, but the middle rocks on the hill just outside Bonnie Springs are simply not there, and this is the same all around the wasteland for that particular set of rock pieces. I'll try to look up the meshes tomorrow but you can just as easily do that and know what your looking at/for. I'm not a modeler so you'll have to be quite specific what I should be looking for if you want me to look. Although I would suspect that the mesh is either broken or not being read or something because other people have generated LOD with that mesh.
All of the Red Rocks are using the normal for the diffuse texture, it quite visible up close.
