[Chimera-users] help with raytrace

Hi Corey,

  This is a Chimera bug.  If you use "movie record <some options>" then 
"movie stop" then you use "movie record <other options>" in the same 
session Chimera ignores the options to the second movie record and just 
uses the ones you specified on the first movie record command.  There is 
some sense to this because if you for example change the recording 
directory of filename pattern then later try to do a "movie encode" it 
is going to generate an error because it doesn't keep track of the 
places and names and you gave to the files in the different recorded 

  There are two ways to handle this: 1) use the same movie record 
options for all frames (raytrace all frames), or 2) restart Chimera if 
you want to change movie record options.  I think method 2 will also 
start numbering the frames from 0 so it will overwrite frames if you put 
them in the same directory.

  I'll create a bug report for this so it does not behave in such a 
confusing way.
