David,<div><br></div><div>Then my *guess* is that you have actors/pieces of your single actor (some of which may not be visible due to size, etc.) that span such a great distance that the actor you are trying to zoom in on is at a far distance. Some of these may be single points. The camera focal point is near where the zoom function "stops" working. You can either interrogate the actor you are interested in and set the camera focal point to an appropriate location within the actor extent, or you can clean up the scene to get rid of the extraneous stuff that is forcing the camera to back out that far.</div>
<div><br></div><div>Have the camera and the actor do a self print and compare the camera focal point to the actor bounds/center.</div><div><br></div><div>- Wes<br><br><div class="gmail_quote">On Tue, Dec 15, 2009 at 1:44 PM, David Doria <span dir="ltr"><<a href="mailto:daviddoria%2Bvtk@gmail.com">daviddoria+vtk@gmail.com</a>></span> wrote:<br>

</div>ResetCamera() (pressing r) puts the camera back at its original<br>
position (zoomed way out).<br>
