I am trying to create a movie that is morphing between 3 atomic models while simultaneously morphing between the 3 corresponding volumes. The following is my script for recording this movie:

There are 4 maps in my morph, but the fourth map is simply a copy of the first in order to mimic the wrap true option of the atomic model morph. I am encountering the following issue during the volume morph step: somewhere in between the morph between volume #14 and #15, the map disappears for a fraction of a second in the movie. I suspect its because of a calculation/waiting issue, because if I record the movie using filtered versions of the volumes (volume guassian sDev 2), I don't have the same issue.

Am I correct in my interpretation of the issue? Is there a way to modify my recording script to avoid this?

Thanks,
