[Chimera-users] zone tool in volume rendering

I've been using the new mask tool to extract features along surfaces,
which is useful in its own right for generating separate maps of
segmented areas. but, if I wish to color a region around a surface (or
between surfaces) without generating a new map, I am not sure how to do
this - the 'zone' and 'color zone' tools in Volume viewer expect atoms
or marker files.
I had thought about loading multiple files of these surface regions
after segmenting them out, each with their own color, but loading them
together produces the ordering problem with the volume rendering. also,
loading multiple volumes consumes a lot of memory and I run short of memory.
is there currently a way to color arbitrary regions in a volume rendering?
for example, rendering all data within 60 A of a surface with a
different color than the rest of the volume, or coloring a region
between two surfaces a different color, analogous to the 'sandwich'
option of the mask tool.
