Detailed Description

Distinct materials as modified by physics.

User-selected regions can alter physics properties so that the same "geometry material" can correspond to multiple "physics materials". These include the behavior of the material as an optical region.

• geo_material_id is a geometry material corresponding to the index in the ImportData.geo_materials
• optical_material_id is an optional optical material corresponding to the index in the ImportData.optical_materials

Geant4 requires an optical material to correspond to a single geo material, but we may relax this restriction in the future.
