The Three Broomsticks was a very fun Portkey to create! The icon inn/restaurant/pub is beloved in the Harry Potter Franchise, so bringing it life was a real treat. I had full ownership of the environment. It was really nice making an environment the fireplace as the main source of light and focal point.
Being a mobile game we were very limited on draw calls, vertex count, and per pixel shaders. Although most of the textures are created PBR style we end up baking it all down to just diffuse only for performance reasons. There is a little bit of image based lighting used for a few of the metal objects within the scene.
The environment is lit in the Unity game engine.
