Joris, you should be able to apply different transparency settings if your proteins are part of different objects i.e. set transparency=0.8, sel1 set transparency=0.5, sel2 HTH Carsten

Is there a nice way to give pymol more priority/RAM to do difficult (big protein particle surfaces) ray tracing? Or would POVray do a better job at that? Thanks a lot.
