Finally got them to work. 

My HatHair morph is working pretty well & can tweek as needed easily.

The hair is https://www.daz3d.com/hs-gloria-sleek-and-wet-short-hair-for-genesis-9-8-and-81-female

I haven't surfaced it fully yet. It's deceptively simple looking but has four layers, each with separate maps. Too bad I've most of it under the hat.

Thanks guys.
