How do you light 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 good are unity graphics?
Its all cool, but kind of wrong and not good if you look at it in the details. Still unity has alot off benefits and the graphics are good enough. But if you want to make the greatest visuals posible, unity is not the way to go, unless you are a full in openGL programer and rewrite most of unitys features.
What does it mean to have realtime 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.
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.
Why do we use indirect light in Unity?
Most frequently it is indirect (bounced) light that we want to store in our lightmaps when trying to create realism in our scene lighting. Fortunately, this tends to be soft with few sharp, or ‘high frequency’ changes in color. Unity’s Precomputed Realtime GI solution exploits these ‘diffuse’ characteristics of indirect light to our advantage.
Why are shadows black in realtime in Unity?
Note that shadows are completely black as there is no bounced light. Only surfaces falling within the cone of the Spotlight are affected. Realtime lighting is the most basic way of lighting objects within the scene and is useful for illuminating characters or other movable geometry.
