Introduction to Reflection Probe

Introduction to Reflection Probe

The reflection probe is a powerful tool in the Unity engine for simulating the reflection and refraction of light in the scene. It can add real-time environmental reflection and global illumination information to game objects, improving the realism and visual effects of the scene. Reflection probes are widely used in real-time rendering, virtual reality and augmented reality and other fields.

How to use reflection probes

In Unity, using reflection probes requires the following steps:

1. Create a reflection probe: Select a game object that needs to add reflection effects in the scene, and then select "GameObject" -> "Light" -> "Reflection Probe" in the menu bar to create a reflection probe on the game object needle assembly.

2. Adjust reflection probe properties: Select the created reflection probe component, and in the Inspector panel, you can adjust multiple properties to control the reflection effect, including the position, size, update interval, reflection resolution, etc. of the reflection probe.

3. Bake the reflection probe: After adjusting the position and properties of the reflection probe in the scene, you can choose to bake the reflection probe to the scene (Bake). Baking saves reflection probe information into textures to improve performance.

4. Apply reflection probe: Apply the baked reflection probe texture to the material that needs reflection effect. Select the material to be applied, find the reflection property in the Inspector panel, and select the corresponding reflection probe texture.

Reflection Probe Example

For example, in an interior scene, you can create a reflection probe on the ceiling to simulate the effect of the ceiling on objects in the room. You can adjust the position and size of the reflection probe so that it covers the entire room. Then, apply the baked reflection probe texture to the materials that need reflection effects, such as floors, walls, and furniture. In this way, when the game is running, you will see the real-time lighting and reflection effects of the surrounding environment reflected by the objects in the room, which enhances the realism of the scene.

I hope the above introduction, usage and examples of reflection probes can help you. If you have any other questions, feel free to keep asking!
