Hello,

I was wondering if there is a way to utilize "util.mroll" when the movie script 
contains "mview" declarations? I saw some similar questions, and the answers 
were mostly workarounds (e.g. 
http://www.mail-archive.com/pymol-users@lists.sourceforge.net/msg07237.html or 
http://www.mail-archive.com/pymol-users@lists.sourceforge.net/msg07661.html).

Ideally I would like to switch smoothly between several camera angles with an 
"mview" statement, perform a 360 camera rotation and show some other 
representations after that. The reason I would prefer "util.mroll" is smooth 
camera movement. Compare, for example, these two scripts:

#util.mroll
fetch 2ke8
mset 1 x300
util.mroll(1,300,1)
mplay

#turn y
fetch 2ke8
mset 1 x300
python
for f in range(0,300,100):
 cmd.frame(f)
 cmd.turn('y', 120)
 cmd.mview(action="store")
python end
rewind
mplay

Hope this makes sense.

Thank you,
Vitaly
