So, I have been transferring 3D Scanstore scan with Headshot V2 and it does an amazing job. However, It transfers my Color and normal maps but won't transfer the roughness, which makes a huge difference in matching the appearance. 

Is this something it can not do or am I missing something? I brought in the scan mesh and piped in the color, normal and the spec

Also, can i add a channel for gloss in the human skin shader?
