Gang-
Thanks for leaning into my inquiry. Still stumped and frustated by my work arounds thus far.
L.R. I have attached the .cga file. Thanks in advance for taking a look.
David- The back face culling does toggle on/off the visibility of assets....except those generated with the schematic_city.cga rule. Reference pic.
The lack of texture on the building geometry is preferred in this instance but would ideally be able to select from 3-4 ground plane (LotInner) options via the script. Reference creative direction below.
Again...grateful to support of ESRI community.
