title: How do I stop a camera from rendering to a RenderTexture?
body: <p>I have a camera in my scene that has a Target Texture set as a Render Texture. I want that camera to render the scene into the Render Texture, but then stop rendering anymore, essentially freezing the frame into the Render Texture. How can I achieve this? Disabling the camera or setting its target texture to null seems to just make the Render Texture appear invisible.</p>
