Greetings,

As will no doubt be obvious from my question, I am a new opendx user.
I have spent time going through the tutorials and reading the online
documentation, but have not found (or perhaps recognized) information
to resolve my problem.

I have a pair of 2D scalar arrays, one representing a height field in
meters (400-1660) and the other the percentage of coverage (0-100).  I
believe these are both position-dependent samples in dx terms.  I
would like to use the elevation array with rubbersheet to build a
terrain model, and color it using the coverage array with a colormap.
I have tried several variations of networks without success.  I found
that passing the output of rubbersheet to normals adds a colors
component, and thought that I should be able to use lookup to replace
that component with the colors component out of colormap, but that
does not seem to work.  I believe I am foundering on the issue that
the elevation data is being used to look up a colormap element, and
is therefore always out of range.

This would seem to be a common activity, so I am probably missing
something obvious.  Any hints or pointers to the relevant
documentation would be greatly appreciated.

Cheers,
Duane Gustavus
