[Chimera-users] drawing ribbon

I have a protein with 10 transmembrane domains and would like to make a movie in which the ribbon is drawn in time from the N- to the C- terminus. I wrote a script that does that. But, the 10 transmembrane domains become hard see because they overlap one another. To solve this problem, I wanted to make the first 600 amino acids become 70% transparent after they had been drawn. Then the drawing would continue with the second half of the protein with no transparency. The problem is that the script that I have written to do this draws the first 600 amino acids 70% transparent immediately as they are drawn. Then the second half of the protein is drawn with 0 transparency. I set the wait time to 600 because I want to execute the transparecny command after the first 600 amino acids were drawn. But, instead, the drawing of the first 600 amino acids is tremendously slowed down by this command as if a wait of some duration occurs after each amino acid rather than after all 600 amino acids. I would appreciate your help. Thanks.
