Unity Editor - Create a custom scene view

Hello,

You can create a new RenderTexture and assign it to the targetTexture of your camera.

proof that it works:

 using UnityEngine;
 using System.Collections;
 
 public class test : $$anonymous$$onoBehaviour {
 
     public RenderTexture text ;
 
     // Use this for initialization
     void Start () {
         text = new RenderTexture(400, 200, 200);
         camera.targetTexture = text;
     
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 }

attach this script to the camera in a scene.

a RenderTexture Inherits from: Texture so it should not be a problem to display it as a GUI element

Thank you but this is not what I want. I would like to create a new scene view, like a preview window.

It is possible, but not very easy. You could use GUI.DrawTexture to draw a RenderTexture like @Nerevar mentioned. This texture will be used as the target texture of a temporary camera that you new up to preview your model or whatever. But then you'd have to detect panning etc which gets weird quickly.

Alternatively, I don't know if this works for you but you could create a new Scene 'tab' - Right click on the current open scene tab | Add tab | Scene.
