So, to keep things as short as possible, I'm working on a custom interior cell. I want to add a custom flag to it so I duplicated the usflag01 model into a new form, created a custom texture set, assigned it to the new flag and placed said flag into the interior cell. All works perfectly in GECK, as illustrated below. It also works in the render window, but I forgot to make a screenshot and have since deleted the flag (work files still available): http://i.imgur.com/Uk5tP9Q.png The problem is that whenever I load the game, the textures get replaced by something like this: http://i.imgur.com/44WSHAW.png Or more recently, the black scan line background of a terminal. I have no idea why that happens. The custom textures are in the /data/<my_exact_esp_name>/textures/clutter/flags/ folder (exact naming. Could it be wrong?). I also tried putting them directly into the textures folder (/data/textures/), but to no effect. They're in the right place (I think), but the game doesn't seem to be able to find them and just replaces them with the next thing on the list of textures. Just to humour myself, I copied the usflag01 diffuse and normal maps as they were, without editing, without any modification, just copied them, renamed them accordingly and put them in the same folder, just to see if the editing software I use is corrupting the files, but it isn't. Same files in two different places, the ones in the textures folder just won't load. What could be the problem? I've been into GECK modding a whole ONE DAY, and I've come up to my first unsolvable problem. That can't be good. :D
