What is Ambient light in Unity?
Ambient light is light that is present all around the Scene. It doesn’t come from a specific source or direction. Instead, it is applied equally based on the normal of the material. It is also known as diffuse environmental light. It can also be referred to as world lighting.
Ambient Lighting has a crucial impact on the look of your scene. It can also have a big effect on the overall brightness of your scene.
What color should ambient light be?
Soft colors work best. Try not to overdo it. Use a low brightness and low saturation to add a little bit of lighting throughout the scene. If your ambient light is too strong, it will wash out your directional and punctual lighting. If you have a skybox, it is often best to use the Skybox Material. Using the Skybox Material will provide realistic, slightly uneven ambient lighting to help your scene feel grounded.
