Thomas,

If you comment out the h_add line in the pml script below, the surface looks 
good.  If it's in there, it's broken for me.

Cheers
Markus

<broken_surf.pml>

# load the PDB file
fetch 3CIY, async = 0

# add hydrogens
h_add 

# hide everything but show cartoon
hide lines
#as cartoon

# show protein surface
show surface, all

# deselect all to avoid little pink squares
deselect

# hide non-polar hydrogens
hide (h. and (e. c extend 1))

# finally, raytrace and save a PNG
ray 
png broken_surf.png

</broken_surf.pml>

Hi Markus,

I can't reproduce this. Do you have an example?

Thanks, 
  Thomas
