I have a map with model docking and am making movie. My plan is to fade away the map to show the docked model for next step. I tried the crossfade which works.

But I want to use the transparency command for this purpose because I want to keep the map at specific transparency level, like 80%. 

The chimera has command like 'surftransparency 80 #1 50'. I was wondering what is the similar command in ChimeraX?

Thanks and cheers,

Yanhe
