Hi Steve,
following code works for me, I will let you compare and find out about
the issue :)
I didn't change much I used your code where you generate the cube,
just be aware, as you start the app the camera is inside the cube and
you have to zoom out to see the entire cube. Find attached the
screenshot of the cube (after zooming out)
Best,
Ozgur
