How to use multiple cameras in same model for mirror (if that's the only way)

Hi all

I am creating a shot where the camera pans on a range of objects on the table which is a mirror. Now, I want the reflection in the mirror to move when the camera moves just like in real life. But I can't understand how do. a technique that I've imagined is to create another device and place it on the surface of the mirror and then have somehow connected to the main camera so that it records the image while moving the way ray of light will react on the main camera. later, I can make that camera mirror to place videos in the model so that it looks like a reflection on the other hand. But then again, I don't know how to establish that, as I don't know how I can connect a camera with the main camera that also reacts to the movements of the cam as a reflection of the light. Is there any expression for her? Help, please.

Thank you.

Here is a version of CS6 project: reflections (CS6) .aep

It's corrected workflow

  • In the model of the hand, make sure that the mirror of anchor point is in the center of the layer and the scale is 100%
  • In the project Panel duplicate the model containing the 3D scene
  • Rename duplicate reflection
  • Open the model of reflection for editing
  • Here is where the fun begins. Select the lights and the 3D layers and their parent to the mirror
  • Make sure that Local axis mode is selected in the toolbar
  • Select the rotation tool and make sure that it is set on the direction
  • Move the cursor on the y-axis of the mirror, hold down the SHIFT key, and rotate the x 90 ° mirror (should be the 4th snap)
  • Select the scale property of the mirror layer by pressing the s key
  • Disable the locking of the scale, then set it to x-100% scale
  • This should reverse the lights around
  • Divide the timelines and reveal the position of the cameras properties
  • Add an expression to the camera position of thinking Comp by Alt/Option click on the stopwatch, and then drag the pickwhip to the model of the camera hand Position
  • Nest the Comp "reflection" in the original model and condense the transformations
  • Make a duplicate of the mirror layer and use it as a track matte for the model of reflection
  • Set the properties of the layer of mirror to get the final look wanted by using as an adjustment layer or change the material options or specular blend modes to pick up

That should do it.
