A maybe better option would be using the „points“ representations instead of VDW. It is also massively faster in terms of graphical performance.

Hi Damien,
Each atom is scaled according to its radius. I think VMD "knows" based on the mass what the radius should be, and sets it to different radii by default. Using the tkconsole, you can override this trivially:

[atomselect top "all"] set radius 1.0

Then you would get the same radius for every atom.

Dear community,

Is it possible to change the radius scaling in CPK drawing method ?
I would like to change the VDW scaling in order to have all my atoms with the same radius (for example carbon atom radius for everyone).
