[chimerax-users] making color zone transparenct

[Elaine Meng]

The annoying workaround for now is to make the atoms/markers transparent before doing the color by zone.  E.g. if the atoms or markers are #1, command:

transparency #1 50 target a

The transparency command default is to only affect surfaces, so “target a” is needed to specify the atoms.  If you don’t want the atoms to be transparent, you can change them back to 0% transparent after doing the color by zone.

I hope this helps,
Elaine
