[Chimera-users] Z-slice transparency

[Tom Goddard]

Hi Lu,

  I think I know why the volume planes are slightly transparent for 
you.  You are using Chimera version 1.2422 and I changed the volume 
solid rendering transparency behavior in the later Chimera version 
1.2434 (August 3, 2007).  You can either get the most recent Chimera 
from the daily builds web page:

    http://www.cgl.ucsf.edu/chimera/alpha-downloads.html

Or in older Chimera versions use volume menu entry Features / Brightness 
and Transparency and change transparency to 0.  You'll have to type this 
in the entry field and press return because the slider does not go all 
the way down to zero.  This transparency value modulates the 
transparencies given by the height of the brightness / transparency 
yellow curve on the histogram.  Newer Chimera changed the modulation 
behavior to keep completely opaque voxels still completely opaque while 
older Chimera did not.
