[chimerax-users] transparency

[Tom Goddard]

Hi Krishnan,

If you use "volume morph" then it interpolates the map color and transparency from the first map to the second.  So if the first map is 95% transparent and the second is 0% transparent that would match what you saw.  You can use the "interplateColors false" option to the volume morph command if you don't want it interpolating color and transparency, or make the second map 95% transparent.  See the documentation for volume morph
