RE: [PyMOL] Overlapping surfaces

[Warren D. <wa...@de...>]

Hugues,

1) PyMOL will not render identical overlapping surface triangles =
correctly -- it is a weakness in the current algorithm.

2) If the surfaces are truly distinct are distinct, then you'll only see =
one of the unless you select multilayer transparency, in which case =
you'll see both sides of transparent surfaces (which doesn't look so =
great either).

Sorry!

Cheers,
Warren
