CFG4 PMT Edge Double Reflect

[RESOLVED] Containing Material placeholder leading to DUD in buffer

Resolved by change order of App::prepareOptiX and configuring the analytic PMT containing material.

Issue

Boundary issues with:

ggv --analyticmesh 1

Planting an assert to see where the GMaterialLib CLOSE is coming from:
