Question by yui21 · Jun 14, 2020 at 10:44 AM · rendertexture

RenderTexture update

     public Camera Cam;
     public GameObject Quad;
     RenderTexture rt;
     public void Start()
     {
         rt = new RenderTexture(200, 200, 0, RenderTextureFormat.ARGB32);
         Cam.targetTexture = rt;
         Quad.GetComponent<MeshRenderer>().material.mainTexture = rt;
     }
     public void Update() {
     }

I want to do something simple.

  1. Create a RenderTexture

  2. Render camera content to it

  3. Use it as a texture

However, the code above doesn't update the render texture. It only shows a skybox although an object is placed in the scene.

Is there any help?

One more additional question. When I encounter this kind of problem, where should I go? This is too simple to ask here but the Unity manual doesn't provide sufficient information.
