While looking through the 'creatures'-records for another mod I noticed that the game includes the code for the Trogs from Fallout 3: The Pitt DLC and decided to integrate them to the Ghoul and Centaur spawn similar to how I integreted Mirelurks to Lakelurks.

This mod adds Trogs towards the Ghoul and Centaur Leveled Lists
There is an chance that 2 Trogs spawn instead of one Centaur

If TTW is not loaded it increases the Trogs fatigue to match TTW and removes Karma from killing them

It always updates the TrogFaction so there is no infighting between Trogs and Ghouls/Centaurs and there allys/friends

IMPORTEND: The game does not come with textures for Trogs so here are some legal ways to get them:
1. Extract from Fallout 3 bsa (which I expect you have gotten legaly and should work regardless of if Fallout 3 is censored or uncut):
 - get an bsa extractor/browser
 - open the The Pitt - Main.bsa
 - textures\dlcpitt\creatures\streettrog and extract all .dds files from that ordner.
2. Use TTW.
3. Download Trog and Factory Protectron 2K or The Pitt 2K by Phlunder: they are Fallout 3 mods but since it is only textures there should be no problem.
4. Download Desert Natural Creatures by Arccharger448: Trog textures are included in the mod and it includes many more creatures, you might want to download one of the above mods for normals otherwise the textures might look flat.

note: If your Trogs glow brighter than the sun then it is an mod conflict between your textures/normals and skinned mesh improvement mod. I do not know what exactly the conflict is but during testing the Trogs changed back to normal after hiding SMIMs Trog meshes.
