It coulda been the one by that Nance guy http://www.renderosity.com/messages.ez?Form.ShowMessage=45204 With regard to controling the Depth Cueing, it is not calculated by the distance from the camera, but rather from the nearest object in the scene to the farthest object in the scene. This allows you to control the DC a little bit by placing hidden objects in the scene to affect this distance calculation. Place an invisible box in the background and continue to move it farther back from the camera until your foreground objects render with the desired opacity. Not great, but a little flexibility.
