I ran into the same issues with missing meshes and textures but I use Beware of Girl replacer because I think it better matches the skin tone of Fallout Redesigned. However, they are both Type 3 and the DIMType3clothesRetail.esp is a standalone fine. I installed it and it worked great. Thanks for figuring this out.
When installing the Unofficial Fallout 3 patch, the instructions say to install the update via "Merge". However, Merge is not an option. MO doesn't automatically give the Merge option and there's no manual merge option. How is this supposed to be done?
