Hi Desiree,
I'm not totally clear on what you are trying to do.  Morphing is only for changing the shape of something, not whether or how it is displayed.   You would use morphing to show the difference between maps from different experimental conditions, or between different conformations of an atomic structure.  

General information on making movies:

With the volume command you can change from solid to mesh and with modeldisplay command you can hide and show models, including maps and/or atomic structures.  Those things happen abruptly, however.   If you just mean you want to fade in and fade out things gradually over several frames, it can be done with the movie command crossfade option, but only if nothing is being moved during the crossfade.

If there are movements (position changes) occurring concurrent with the display changes in your desired movie, you could try using the new Animation interface (you would need to get Chimera version 1.7, i.e. a recent daily build).   You would save "scenes" and then arrange them on a timeline, and then Animation would take care of gradually transitioning from one to another.

Daily build download:

I hope this helps,

Should I save each form (i.e solid, mesh, etc.) individually and then use a morph command to progress through each one? (If this is the case could you give me an example command line I could refer to?) Or would this involve setting all of the models up via command lines as the movie was recording?
