There are several ways to solve the problem:
1) Replacing files
- Open: SWATofficerTex, SWATheavyTex, SWATnoArmourTex
- Replace files: textures, normal map
This Way doesn't fit. The editor can't export a normal map. You will have to create them yourself in Photoshop.
2) Editing Shader
- Open SWATofficerTex, SWATheavyTex, SWATnoArmourTex
- We open the shader you want
- Replace the texture paths and the normal map
The easiest way at the moment. Check this video. You should not have any difficulty with this.
3) Compile the main file to change the name
It's not an acceptable option. You'll probably break the game.
Good luck, officer!
