Hi all, I enjoy very much using chimera, I have a question regarding surfaces. When I am working on a multi chain protein complex, and I want to present only one chain as surface and the others as ribbon or sticks, oftenly the surface present "holes" on the contact points with the ribbon. I understand they represent contact points between the chains, but I don't like how the surface looks like. Is there a way to avoid this? (I do that but uploading another copy of the chain).
