I use iMac. The version of VMD is 1.9.3. There is a .vmdrc file at /Applications/VMD 1.9.3.app/Contents/vmd/
You can copy this file to your home directory ~ and then modify it.
What I want to modify is turn on all four lights, remove the axes and change the background color to gray.
The following modification is based on the original file from VMD.
- line 25: light 2 on
- line 26: light 3 on
- line 29: axes location off
- add color Display Background gray somewhere
