Bot material (packed textures)

Hi All,

I am trying to understand how the M_DPW_Bot material is setup. As its a complex material with lots of packed textures.
I would like to use this material setup for my own model. Does anybody know how the channels are setup. As I want
to export out my textures from substancepainter. Thanks
