[Chimera-users] Problem adjusting sphere quality in script

Hi Richard,

   Oops.  That Chimera code for setting the quality was wrong.  It should be

import chimera
chimera.LODControl.get().quality = 20

The trouble with the original code is that it set the quality in the 
level-of-detail control class instead of the in the specific instance of 
that class being used by Chimera.

   I'll fix the online movie course material that had that incorrect 
code.  Thanks for pointing out the problem.

> When I open this script like in the tutorial, the value of "subdivision quality" in the "Effects" panel is indeed set to 20. However, the quality of spheres and cylinders remains untouched. From that point in time any further modifications of the value in the "Effects" panel do not have any effect.
