Hi Elaine,

following what you wrote, could be more precise on the meanings of start and end:
Manual:
depthCueStart start
depthCueEnd end
Set the position of the depth-cueing ramp. Depth-cueing shading increases linearly from start to end, each expressed as a position relative to the front (0.0) and back (1.0) global clipping planes (0.5 to 1.0 in simple lighting).

- What is the start really? Is it where the viewer/user seats on his chair? Because if I use your command I get a certain depthcue, but if I zoom on the structure and use the same command it doesn't change the depthcue.
- Is 0.2 the relative start of the PDB file?
- Where does it end?
- is it related to the Side view bars?

Thanks for these clarifications.
Vincent
