How do i go about fixing this problem?

What's the problem? The missing texture on the white thing?

I assume that you are trying to impliment that bo2 model, and it is completely white which you maybe don't want.

Then you don't have the textures/images files for it yet. If you already have the images for that model, then copy all the .iwi files which is the files of the images and paste them in,

root/mods/mapname/images/

Now if you don't have a folder called "images" then just make one.

If you don't have the images converted in WaW yet, then do this.
Open launcher and look in the IWD list on the right in the "built mod" tab, then look after your images files and check them.

Now to convert the images, build your mod with only the "Build IWD" box checked, and then build your mod.
