Yes, these options only control the anti-aliasing settings for VMD's
Graphics display (and images produced using the "snapshot" renderer).
For other renderers, you'll need to set specific options -- either in
the rendering command or (possibly) the scene file produced by VMD -- to
produce anti-aliased images.

In Raster3D, it looks like you can achieve anti-aliasing by adding the
"-aa" option to the render command. Let me know if you need any help
doing this.

Hope this helps,
