Scene Graph Basics Not Working and/or I'm Missing Something Basic

Hey all,

Know it’s still experimental, but I’m trying to do something very basic with Scene Graph and just can’t seem to get simple stuff working right with it.

I’m just trying to add a very simple ‘custom’ mesh that is a playing card back, a.k.a. a simple poker-sized cube, as a mesh component. …So I select mesh-component, it defaults to a cube, and when I select any custom mesh… it stays as a cube. No tutorials online seem to address this and I’m frothing at the mouth at this point in trying to get it to work. Any idea what I’m doing wrong?

Thanks in advance for any suggestions.
