Phong + Specular Soldiers (EP2)

Both specular highlights and cubemap reflectivity of EP2 and original HL2 shading for Combine soldiers. This version overrides the soldier’s materials to always use their dirt covered EP2 versions so only enable it when playing EP2. Alternatively move and rename the .VPK of this addon into the ep2/custom folder.

Description:

Materials and textures adjusted to support both original pre-orangebox specular shading and the original EP2 phong shading.

HL2 version

Features:

• HL2 and EP2 supported.
  
• Uncompressed normal maps.
  
• Enhanced shading.

Custom texture setup:

The normalmap's alpha channel is the phong mask. The original dedicated phong exponent texture is used. The diffuse texture alpha contains the specular envmap mask. The original dedicated selfillum mask texture is used.
The phong and specular vmts are then combined using this approach and the $envmaptint values are halved since phong doubles the intensity of the envmap otherwise.

To use custom textures, simply export the alpha channel of textures from this mod and replace the alpha channel of the custom textures. Then copy over the .vmt files from this mod.
