Model Overlays

I’m trying to make a skin using the distortion (DUDV) shader, but I also want an overlay over that so that it has symbols and “frost” so it looks like some ice-science hybrid. This is for the mod for Portal “Blue Portals.”

So basically, how do I make it so a model has an overlay? And how do I make the VMT work with the overlay/s?

seems like you should be able to make a mask for the distortion shader. Does it have that ability?

Well I found out all I could do was add a color overlay to it. So it looks like this now:

Still a WIP, though.
