I am working with a 1250 x 1000 gif file in 256 colors. This is used in a
height_field.
Regardless of how much I scale the scene I can only get the color_map to
work within the range 0f 0 and 0.1.
Any ideas !!

As a test I rendered a smaller (480 x 360) gif height_field from the front
edge
then used identical settings with the larger image
I tried using a vertical scale at both 250 and 500.
With the smaller image the results were quite predictable and OK
With the 1250 x 1000 file the image was correctly scalled but much too low
in the view
and the color_map only reflected the scale of less than 0.01 !!

What is going on ?
