I have the following:
I also have Mart's Mutant Mod, but its currently disabled.
The first mod I downloaded was children of the wasteland, and I noticed that the hair textures were detail-less and blank. Then I finally found the cute shop, and all the clothes are also missing textures.
I thought maybe I didn't download it right so I just decided to deal with it until I feel like going back and "reinstalling" it.
Then I downloaded Mart's Mutant Mod, and I noticed that vanilla monsters now have messed up textures as well. Their textures weren't exactly "missing". If I looked at a molerat, it would sometimes show its normal texture. But if I looked at from another angle the molerat would then switch textures to close by objects. Such as dirt, or rocks.
I went ahead and manually removed it, then carefully downloaded it again but it still gives me the same problem.
Both of these mods have texture problems and I'm not sure if I'm to blame, or if somethings wrong... If anyone could educate me, I'd be very appreciative.
PS: If it makes any difference I was advised not to download my Fallout 3 game in "Program Files" but to instead install it directly into the "Bethesda Softworks" file.
