Elaborate please, When i say i'm new to this i mean Blender as a whole. I've only really just gotten the hang of the bare basics.

New to this and i want to start ripping models from goldsource games and it would be helpful to know how to get chrome textures to work in Blender (Example being the Vortigaunt's shackles being compeltely black instead of the texture working as intended). I know it's possible but i don't have a clue where to start if fixing it can even be done in Blender itself. Would very much appreciate the help, Thank you.
