Just dragging the BP into the scene now shows the 8 x 8 set of chairs. Yay finally.
I’ll go back to my mesh created from a primitive cube now, and if that works I’m set. 
[EDIT: Yes that now works, thank you all for the help]
[EDIT 2: Generating alternate squares as a chessboard now, using my primitives(converted to mesh), so I need to understand how to tie each of these into clicking and hoverable squares, procedurally as well). Save that for another day. ]
