[PyMOL] Issues when displaying surfaces of two objects in two distinct display grids

[Vedat D. <ved...@gm...>]

Hi altogether, 

using Pymol open source 2.4, I'm trying to simultaneously display two
objects (OB1 & OB2) side-by-side in a grid (>Display>Grid>By object). So
I have one object (OB1) on the left part and one (OB2) on the right.

Now, in order to have two surfaces on the left covering different areas
of the protein, I need to partially duplicate the object on the left
(OB1). Both surfaces on the left are shown properly.

But if I do the same with the second object (OB2, on the right part of
the screen), I run into issues: for none of the objects created as
duplicates (copies) from OB2 I am able to display the corresponding
surface. For the original object (OB2) it works. But this is not what I
want.

Does anyone know what's going on and how to circumvent this problem?

Many thanks in advance & best wishes,

Vedat
