Thanks for the replys so far :) I use this mod for testing if it works. (Bodytextures does not work aswell, so do Rock textures etc.) Its just the rifle to keep the list of errorpossebilitys slim. https://www.nexusmods.com/fallout3/mods/21152/? I will try to recreate the ini files, but MO uses its own ini files. so the Launcher will use different ones.. wait... brb testing... Edit: Okay... chaning the ini does not fix anything. But somehow my "Blank" Profile now has the correct rifle texture. But rock textures still are bad vanilla. Edit 2dn: I found out that at least for a fresh installation of Mod Organizer with nothing except the Rifle texture mod, works. So my Problems seem to be mod specific, and not related to Archive invalidation. Edit 3rd. But somehow it is not working properly. Either most mods i use have a completely messed up dir structure, or archive inv. does not work. If i run the game with the usual launcher everything works fine. So it must be a problem with Mod Organizer. Edit. 4th. But why does it work for the laser rifle texture?? I tryed the following: 1) i added a bodymod to the FO3 data directory and deactivated the archive invalidation with this little 200kb program - started the game - Same messed up Texture like i run it with Mod Organizer. 2) reactivaed archive invalidation again - started the game - Textures work fine! 3) I coppied the laser rifle mod to the FO3 data dir - started the game - textures work. For both, body and gun. 4) deactivated archive invalidation - start the game - Both textures are gone. So far for vanilla Skyrim with no Mod Organizer. 5) Deleted all textures and Meshes form FO3 Data dir. 6) activated both mods in mod organizer. - started the game - Bodytextures Messed up, rifle textures are fine... wtf?! Can anybody explain?
