[PyMOL] shade on transparent spherical surface

[SongJianHui <gi...@ho...>]

Hello, everyone,

I've been trying use pymol to generate an image based on C-alpha coordinates only. I tried to set the sphere to be transparency by the command "set sphere_transparency, 0.5". However, the surface of the sphere shows some shading which looks quite odd. If I ray trace the image, the surface looks nice but it is solid rather than transparent. Any suggestions? Thanks.

Best,
