No i did not navmesh the area, as they seems to be able to move around without problem, the frustrating thing is that these npcs just stand there doing nothing looking silly. I strike them, and they didn't even bother to hit me in return. Look at the pics to the colosseum here, it's all nicely done, but without the enemies, it's kinda useless mod. http://skyrim.nexusmods.com/downloads/file.php?id=12666 Not promoting my mod, just that I couldn't figure out how to put images here. Very discouraged and I guess I have to put this mod into the bin. Edit Alright I did one final test, I raised an island on the map of Tamriel at Solitude, I didnt navmesh the area, I took the default enemies and placed them on the island and I went there to see if they would attack me. Once I was on that island, the draugrs came charging at me and I didn't even have to provoke them. So my guess, I must be missing something in the new world. Ok, then why not make the colosseum in the Tamriel map right on that island, yea I thought of that too, and I placed the colosseum on the island, strangely, as I expected it, some mesh and textures don't appear at all making the colosseum look broken. Yes, I did check the box for full LOD on the model mesh itself and still this happens. At time, the mesh loaded but the textures did not making it look invisible. The creation kit in my opinion is somehow broken but not unsable, it just didn't do most of the work right. Actually the stairs leading to the level where the spectators' seats isn't showing, yea I could do away with the stairs but will it look good? lol a colosseum without stairs....... Any suggestions please as I hate to see my effort on the colosseum goes to waste cos I spent a great deal of time on it.
