USDz materials edit app?

Have anyone come by an app where you can add materials to an .

Cadmio is an amazing rendering app on the ipad (currently in public beta) with amazing materials rendering and UX/UI. It´s the perfect match for shapr3d to make realistic renders of your models.
But I would really like to see an AR equivalent of this. Just as easy to add materials to the parts/surfaces. But being able to show them in AR immediately.

I see USDZshare have some attempts making a working app in switfplayground

It would be cool to see what a bigger company/startup/full time ios developer would be able to achieve.
