MaterialInstanceSet
The distinct effective bindings of a scene, each with one index: the GPU material instances of §RVM-7.
In the namespace construct::model. Declared in src/libs/libconstruct/construct/model/MaterialInheritance.hpp.
Detailed description
Two items with equal effective bindings share one instance. Different values give different instances (case A7). The renderer's material module writes one instance row and one parameter range per index.
