Hi, I've been playing around a lot with depthcue-ing but I can't get it to do quite what I would like. I want to display a protein structure, with a focus on one zone and a "heavy" depthcue to have a strong "fog" hiding much of the background (without deleting the residues in the back). my script includes: lighting full #(sometimes I use soft too) lighting shadows true intensity 0.3 lighting qualityOfShadows finer lighting depthcue true depthCueStart 0.1 depthCueEnd 1.0 First, I have selected one residue and setting the rotation around it by using "cofr sel" My max depthcue is with "depthCueStart 0.1 depthCueEnd 1.0". I've tried to change these numbers in many different ways, including negative or very large numbers) but I can't get it to be thicker. Could you help me please. I missed the meaning of these values, so I'm blind on their use.
