i can see through certain floors in my map like hallways and rooms and some outside but some are okay so what is wrong and how to fix

If you use a _blend texture as the base texture that can happen.

Whats the material name?
Have you tried a different material?
Any errors when compiling in launcher?

i don't think the extures have them settings as its the cod 4 textures ??? and nah no error or anything

If your using cod4 texture maybe they may have an alpha layer and you will need to delete the alpha layer. Save. Reconvert.
If not then i would make a _normal and _specular and reconvert the material.
//
Heres how i do materials.
Ex.
mapname_grass_01_c.dds ( color image with blank alpha layer )
mapname_grass_01_n.tga (normal map)
mapname_grass_01_s.tga (specular map)

Then in asset manager in make 2 different materials.
mapname_grass_01 (_c,_n,_s) regular settings.
mapname_grass_01_blend(_c,_n) blend settings.
