render to texture first frame?

Hi,

Hi i’m creating a kind of level map utility. for this i have a game-object with a orthographic camera attached.
what i want is this.

OnStart(){

  • create a RenderTexture
  • attach it to the camera.

}

  • render the first frame.
  • assign the rendered result to a Texture variable
  • Disable the camera

OnGUI(){
render the Texture variable using the GUI.DrawTexture()
}

The problem lies in the second part. what can i use to render the camera for one time only and use this as a render texture. Or is there something in the editor classes which utilizes this.

greetz and thanx in advance

Yes… Thank you… it’s fantastic…
