Hi Chris, (don't know, if my first mail was going on air, so here again)
to reposition the planes 2 and 3 simply open the Windows--> Choreography Window and delete the "translation" chor which is inside the "lattice1"-level of the planes. Then it should be possible to move the planes ;-) I'll add a tutorial on my site later. It's a very simple task to add more planes, too. See attached image (make sure you've deleted the "translation" from the lattice before duplicating, if not you must delete it from both original and duplicate). (Don't know, if you know the next step) To assign a plane to another camera: create the second camera. Select the plane and the camera choose Tools --> Lattice Mapping --> Reconnect. Hope this is helpy, Matthias ----- Original Message ----- From: "mungenast and standley" <[EMAIL PROTECTED]> To: <user-list@light.realsoft3d.com> Sent: Sunday, November 20, 2005 5:34 AM Subject: Re: Look-at question - Updated! > Very interesting, Matthias. > I had not noticed the dropdown menu "Look at point" on the Map Object tool. > I was suspecting that scripting might help for constraining the pitch, but do not know rpl > or javascript. > Thanks a bunch for that!
