the poser shadowcams (lite-cams) are a minor issue, as almost nobody knows how to use 'em, but like the other cams, it can be maddening to try to control 'em with the parameter dials.  that's why they added the 3d-like camera and lite controls, e.g. the lite ball, which is the way ya fly-round in shadowcam (lite-cam) view.  using the shadowcam or lite param dials is the wrong way to attempt a fly-round.
