Create Bare Metal Skin

[MacGynan]

Hi guys. I'm wanting to add bare metallic parts to my P-51D. I know that it has something to do with a Specular Map file but have no idea as to how to create it.

 

Do I just have to manually go into Photoshop and darken areas that do not shine and have shiny parts white.

I also saw green yellow and red maps. I assume that it’s like a black and white map just with different colours.

 

The only way I have gotten it to work is to use Spec Maps made by ED such as the bare metal skin etc.

 

Anyways if you guys could explain this process to me that would be really helpful. Thanks!

 

Some images to demonstrate what I mean:
