whenever i load a race mode or item/weapon/armor mod it always seys missing meshes and texters

Did you make sure that the missing textures/meshes/etc. exist? I know I had similar problems when I was starting to install mods. I eventually figured out that when I unzipped some mods, they created a "Data Files" folder inside of the original "Data Files" folder, which caused the mods to not find their own files. This problem is easily fixed by manually moving the existing files to their proper folders.

If it turns out the missing files do not exist, I don't have a solution.

ok thanks i will check from now on about that its mostly happening with races and new equipment
