I can’t find a direct path to use SUDrawingElementSetReceivesShadows on SUGeometryInputRef
SUGeometryInputRef geom_input
SUEntitiesFill(entities, geom_input, false /* weld_vertices */);
Do we have to go through and loop all faces ?
SUEntitiesGetFaces(SUEntitiesRef entities, size_t len, SUFaceRef faces[], size_t* count);
