What are the four main forms of lighting available in Unity?

The four main forms of lighting available in Unity include Directional Light, Point Light, Spot Light, and Area Light.

Directional Light simulates sunlight and illuminates all objects in the scene from a specific direction, providing uniform light. This type of light is often used for outdoor scenes to create shadows and highlights effectively.

Point Light is designed to emit light in all directions from a single point, similar to a light bulb. It is particularly useful for simulating local light sources and shines uniformly outward from its position, casting shadows and providing depth to a scene.

Spot Light functions like a directional light but is cone-shaped, allowing for more controlled illumination. It is ideal for creating focused beams of light, such as a flashlight or stage spotlight, therefore adding dramatic effects or highlighting specific aspects of a scene.

Area Light is a bit different as it emits light from a rectangular or disc-shaped area rather than a single point. This creates soft shadows and is particularly useful for simulating large light sources like fluorescent fixtures and providing a more realistic spread of light.

The other options include lighting types that are either not directly classified as standard light sources in Unity or contain elements not typical in the main categories of lighting, such as "Bloom" and "Halo," which
