Render Texture

【Render Texture】

　　Render Textures are special types of Textures that are created and updated at runtime. To use them, you first create a new Render Texture and designate one of your Cameras to render into it. Then you can use the Render Texture in a Material just like a regular Texture.

　　The Water prefabs in Unity Standard Assets are an example of real-world use of Render Textures for making real-time reflections and refractions.

　　Render Textures are a Unity Pro feature.

　　　　

　　與Camera結合後，Render Texture能夠用於實現鏡子效果。
