[Chimera-users] Coloring nucleic acid ladder with opacity. Possible bug?

[Greg Couch]

It's not a feature. :-)  For me, transparency for ladder rungs kinda 
works -- the rungs are transparent, but not enough.  And I only see 
opaque white when the ladder rungs are facing the key light.  You could 
mitigate the opaque white by moving the model or the key light.  If you 
are seeing different results or if you're interested in being notified 
after the bug is fixed, please file a bug report.

FYI, in the Chimera daily build (available tomorrow), I've eliminated 
the extra cylinder caps that are exposed when you make the ladder 
transparent, so you can get a slightly better picture.

     HTH,

     Greg
