Might someone have this product?

https://www.daz3d.com/vevenor-ritual-veves-for-genesis-9

Is there some trick to use it?  No docs or vids on YT. 

They're allegedly H.Materials, so I'm selecting the G9 Figure, Rt. clicking a material and nothing.

I own several geoshell products. Geoshells are like second skins.

This product maybe helpful for g8 and earlier - https://www.daz3d.com/geoshell-visibility-presets

This one is for G9 -https://www.daz3d.com/geoshell-visibility-presets-for-genesis-9 

Here is a geoshell tutorial you might want  to add to your wishlist-https://www.daz3d.com/second-skin--the-complete-guide-to-geoshells

Here is a youtube tutorial that might help - https://www.youtube.com/watch?v=pv9a6LocIHE

So, basically I need to make/add a geoshell?

Thanks.

Making the geoshell is the first small part of it.  You have to select the areas that you want to apply the product/presets to. It all depends on the product you are using.

Had the wrong image...

VRV Geoshells from that product wil load the shell onto the figure, then you use the materials on that.

I only have H. Materials & don't see any Geoshells. I'll try one of the links GGreen lists. 

You have to create the geoshell and then apply the materials to the geoshell. The video will explain it to you. 

Friend of mine has this

People>Genesis 9>Materials>Lexa Kiness>Vevenor Ritual Veves

At that path in your Content Library you should find three DUF files, those will load "custom" GeoShells onto G9.

Yay! That did the trick.
