このカメラの設定を他のカメラと同じようにします。
This will copy all camera's variables (field of view, clear flags, culling mask, ...) from the other/
camera. It will also set this camera's transform to match the other camera, as well as this camera's
layer to match the layer of the other camera.
This can be useful if you want one camera to match the other camera's setup, when doing custom
rendering effects. For example when using RenderWithShader.
// Set the current camera's settings from the main // scene camera. camera.CopyFrom(Camera.main);
