[HELP] Creating textures for shield mesh in blender

[Bender321]

Hello, 

I am kinda struggling with creating textures for my custom shield mesh, I just need only basic colors (maybe a metalic look) but nothing too fancy. Sadly I don't know how to create them propelly into .dds files as well as connect them with .obj mesh object. I created that mesh in blender, have .nif plugin but for some reason it yelling at me error that something is out of range in list (python stuff) 

so I exporting it as .obj 

Could you help me how to do it propelly? I really want my shield in game

Look into UV mapping first, then look into making non PBR textures in Blender or GIMP/Photoshop.
