ambient lighting mode for simple drawing style missing
Hi possibly a simple question but it has kept me buffled for two weeks now, so I decided to ask: how can I set lighting mode to ambient? I am trying to create images using a simple drawing style like exemplified in http://www.cgl.ucsf.edu/chimera/ImageGallery/ p53 simple drawing or Clathrin but I don't find ambient lighting mode in the viewing tools - lighting menu. The only options given are lights (head light, 1, 2) or quality (normal, glossy). I am using Chimera 1.5 build 30417 fir darwin 64bit, aqua on a MacBook Pro with Mac OS X 10.6.6.

Hi Christian, You are using an older version of Chimera -- there were many months of 1.5 daily builds before the 1.5 production release in December 2010, build 32133, and the build number suggests you have one of those older daily builds. The 1.5 production release and newer versions include the additional lighting options. A related issue: There was an image-saving linewidth bug that was fixed a couple of weeks ago, but the fix is only in the 1.6 daily build, not in release 1.5.2 (Jan 25, 2011). We are planning a 1.5.3 release for next week which will also have the fix. Since you are working on images, I would recommend either waiting for the 1.5.3 release or trying the 1.6 daily build now and getting 1.5.3 when it is available. I hope this helps, Elaine ---------- Elaine C.

Hi Elaine, thanks a lot for your kind and prompt reply. Updating to the latest version solved all my problems! Best Christian Am 02.03.2011 um 18:28 schrieb Elaine Meng:

Elaine, Christian's question reminds me- if I open a saved session in which ambient lighting was enabled, the reconstituted scene appears to be lit with a combination of ambient and point lighting. I can fix it by going to the effects menu and switching out of and back into ambient, so its not a big deal. But in case its a quick fix, I wanted to report the issue.

Hi Dan, I believe that bug (#9018) was fixed about 3 months ago -- you would need build number 32002 or greater. <http://plato.cgl.ucsf.edu/trac/chimera/ticket/9018> I am not completely sure whether the session with ambient would need to be saved from such a version, or whether it would simply work to restore the session in that version. At most, you would need to open the session, fix up the lighting and re-save in the newer version. If you are still experiencing the problem with sessions saved/restored in the newer version, however, do let us know via "Help... Report a Bug" in the menu. Thanks, Elaine ---------- Elaine C.
