IOS Injustice & MKX texture help??

Been ripping the models from Injustice and Mortal Kombat X and the "SPEC" map has two maps in the file. I've added the files from two models to give ou a good idea of what's confusing me!

I want to make sure I've labelled both Maps properly. This one I've designated these as SPEC maps:

MKX ~ Mortal Kombat X && MKX ~ Injustice:

And this one, I think these are Overlay maps:

Am I right, or have I got it back to front?

Also, I had to rescale the "SPEC" map.

Thanks for the help and what not!
