Hi Dmitry, You could do it using "perframe" with an embedded "volume level" command in your movie script. For example, the following gradually changes map #2 contour level from 2.5 to 0.5 over 50 image update frames: perframe "volume #2 level $1" range 2.5,0.5 frames 50 See the "perframe" help for details: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/perframe.html <https://rbvi.ucsf.edu/chimerax/docs/user/commands/perframe.html>> I hope this helps, Elaine ----- Elaine C.

Thank you very much for your tips. Works as a charm. How 1 more question if you please - Is it possible to record a movie while your 3D map constantly changing its threshold volume level (from low to high - which is possible to set) ? If yes, how? Thank you in advance. Sincerely, Dmitry
Although it would still be nice to have a separate option, currently ndependent rotation can be scripted by using separate turn (or roll) commands as in this example from Tom Goddard:
You can use the "model" and "center" options of the turn command to rotate each model about their own center. For example, rotating 2 models in 1 degree steps around the y axis for a total of 360 degrees
movie record turn y 1 360 model #1 center #1 turn y 1 360 model #2 center #2 wait 360 movie encode side-by-side-spin.mp4
In this example the two models rotate at the same time. The turn command like other commands that create a motion returns immediately before any motion is done to allow you to start simultaneous motions. Then you use the "wait 360" command to wait until 360 frames have been rendered, then the .mp4 movie file is made.
