builtIn constant
The models this engine ships, in the order a picker should show them.
builtIn and not values: there is no longer a complete list to have.
The name says which question it answers — "what came with the engine" —
rather than implying nothing else can exist.
Implementation
static const List<LightingModel> builtIn = <LightingModel>[
unlit,
lambert,
blinnPhong,
pbr,
toon,
normals,
];
