Version 9.0 has been uploaded! It can be found at the Downloads page of this mod. It's still a WIP, so expect some issues.
If you have any other mods, you may already have folders in your Fallout 3/Data folder named the same as the "textures" and "models" folders. To avoid conflicts, just allow the folders to merge if windows prompts you to do so. Its as simple as that, hope I've helped :)
I highlighted key features in orange and the the red arrow shows where and what to drag. Merging is simply when two folders with the same names join.
