How do I set lighting in unity?
By default, lights in Unity – directional, spot and point, are realtime. This means that they contribute direct light to the scene and update every frame. As lights and GameObjects are moved within the scene, lighting will be updated immediately. This can be observed in both the scene and game views.
How do area lights work unity?
Area lights Light is emitted in all directions uniformly across their surface area, but only from one side of the rectangle. There is no manual control for the range of an Area Light, however intensity will diminish at inverse square of the distance as it travels away from the source.
What does it mean to have realtime lighting in Unity?

How do you set up lights in Unity?
To start, open up Unity and create a new project. Before we start placing any lights, we need objects for the light to bounce off of. If we placed lights in an empty scene, it wouldn’t look very interesting! Let’s make a simple room. Go to GameObject > 3D Object > Cube, and adjust it to make it look like a wall.
Do you need to use global illumination in Unity?
Unfortunately, the light rays from Unity’s realtime lights do not bounce when they are used by themselves. In order to create more realistic scenes using techniques such as global illumination we need to enable Unity’s precomputed lighting solutions.
Which is the most performant lighting in Unity?
Baked lighting is the most performant but also the most limiting. Baked lighting allows us to take a “snapshot” of our lighting in game, then create a texture overlay of sorts of all the shadows and highlights calculated from the lights in the scene.
