Alright so I’ve been porting some models lately into gmod, and I’ve been applying the bump map to the model’s skins. However there are 2 more normal maps which I can’t seem to figure out how to apply them to the textures, as well as a detail mask which I have no clue what it is.

If anyone could help, it would be greatly appreciated. Thank you.
