it should own multiple materials and take their respective probabilities in the constructor.
The selection can be implemented with std::discrete_distribution
Something like this:

template <typename ... Materials>
struct Composite : Material {
    Composite(Materials
    auto do_scatter(..) {
        //does not work of course
        return std::get<rng()>(materials).do_scatter(..);
    }
private:
   std::tuple<Materials...> materials;
};
