Hello, The option to make movies using povray works nice and easy, so I want to push the boundaries a bit :-) - the standard texture included in the .pov files has a very simple finish - is there an easy way to include a spiced-up version? - when not using a "wait" command, several movements (roll, move, scale) are combined. When using the wait command, movements become separated with a small "hesitation" before the second movement starts. Is there a way to minimize this hesitation? Thanks, Klaas P.S.: if you know why powerpoint would play a movie fine 3 or 4 times in a row and then fail after that (nothing else changes, except maybe time), please let me know.

I don't know about your other questions but I have some info on this one. Until recently, Chimera was putting an implicit "wait 1" after every line of a script, including comment lines, blank lines, and lines that already end in an explicit "wait" of some sort. Now it does not wait after those three types of lines. Depending on the structure of your script, this behavior may have been causing the "hesitation" you describe. If you get a daily build (www.cgl.ucsf.edu/chimera and follow the "Daily Builds" link) this behavior is fixed there. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu

Hello, We don't have a simple way to change the POV-ray finish. What you could do today, is to use chimera's x3dsave command to export your scene as a X3D file, next run CHIMERA/bin/x3d2pov to convert it to a .pov file, and then edit the result. If the editting is done by a program, you could invoke it and x3d2pov with chimera's system command, so all of the commands could be in a command script. FYI, I will be deprecating the x3dsave command with a more general export command that will let you export directly to .pov before for the next production release. As for PowerPoint, we have a list of troubleshooting web links in the Chimera documentation on "Making Movies". If you have already done what they recommend and it didn't help, we like to know.

Hi Klaas, Here is the Chimera documentation page Greg mentioned: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/movies.html Near the bottom are links to two pages at Microsoft about movie/ PowerPoint issues. However, I just looked at these pages and don't see anything relating to a movie that first plays fine and then won't play, assuming you haven't changed your system in the meanwhile. They seem to relate to cases where the movie has never played correctly. I'm curious: if you exit from PowerPoint and then reopen the presentation, then will the movie play, or does it stop working "forever"? Best, Elaine ----- Elaine C.
