Render Texture

?

is a type of Texture that Unity creates and updates at run time. To use a Render Texture, create a new Render Texture using Assets > Create > Render Texture and assign it to Target Texture in your Camera component. Then you can use the Render Texture in a Material just like a regular Texture.
To create a live scene camera in your game, follow these steps:
  1. To create a Render Texture, go to Assets > Create > Rendering > Render Texture.
  2. Select
    GameObject

    ?

    >
    Camera

    ?

    to create a second camera.
  3. Assign the Render Texture to the Target Texture property in the second camera's
    Inspector

    ?

    window.
  4. Select GameObject >
    3D Object

    ?

    >
    Quad

    ?

    to create a quad.
  5. Drag the Render Texture onto the quad. Unity automatically creates and assigns a material that uses the Render Texture.
  6. Enter Play mode. The quad displays the camera view, which updates in real time.

Render Textures are set up as demonstrated above
