Texture looking transparent

[TSM]

so I make model in blender unwrap it to get texture :-

paint.net I create a diffuse save it as DXT3.dds
paint.net I create a normal using a plugin save as DXT3.dds
then make 3 copies of the diffuse,add 3 new layers red,green,blue,
first diffuse layer I set it hue to 0 0 0,
second diffuse layer hue to 0,0,0 and curve to 55,255,
third diffuse layer I render clouds (dirt)
red layer multiply merge down to diffuse layer 1
green layer multiply merge down to diffue layer 2
blue layer multiply merge down to diffuse layer 3

diffuse layer 1 additive merge down to diffuse layer 2
diffuse layer 2 additive merge down to diffuse layer 3
then save it as DXT1.dds (specular)

Got back to blender and create material, shader GLSL add the 3 textures I created in paint.net

For normal i set (image sampling Normal Map, Mapping UVMap , influence geometry Normal)
For diffuse i set (Mapping UVMap ,influence diffuse colour)
For specular i set (Mapping UVMap, infuence Specular inte,colo,har)

All of the above worked fine for FS15

At work ATM so haven't pulled your post apart but is the model looking transparent without the texture or is it just the texture.. of its the model it's self RE calculate your normals in blender..

Tried that did not help, thanks anyway.
