Empire Strikes Back - is it supposed to look like this

[MudgeeWotto]

Hey all.

 

Wondering if BG is meant to be in a backbox that isnt showing up in my game OR if this is how the table just is? ( just a single flat plane of glass basically )

Not too bothered if this is how it is I just want to know if its how it should be OR if I need to adjust some settings to get it in a backbox?

If you walk around to the side you might see the backbox as it's smaller than the backglass
