The Camera Correction modifier applies two-point perspective to a camera view. By default, camera views use three-point perspective, in which vertical lines appear to converge with height. In two-point perspective, vertical lines remain vertical.

The amount of correction you need to use depends on how steeply the camera tilts. For example, a camera that looks up from ground level to the top of a high building will need more correction than a camera that looks toward the horizon.

NoteThis modifier doesn’t appear on the Modify panel’s Modifier List.

Procedures

To apply two-point perspective to a camera:

  1. Select a camera.
    TipFor best results, set a viewport to this camera’s view. The change in perspective appears both in the viewport and when you render this view.
  2. Apply the Camera Correction modifier.
  3. On the 2-Point Perspective Correction rollout, click Guess.

    The Camera Correction modifier creates a first-guess Amount value for the two-point perspective.

  4. Adjust the Amount and Direction to get the effect you want.

    In the viewports, the camera’s field-of-view “cone” distorts or moves to show the perspective adjustments.

  5. Render the view.

Setting Direction greater than 90.0 biases the correction to the left. Setting it less than 90.0 biases it to the right.
