Elevations shaded with a custom shader will use the color specified for each elevation value. Any elevation
values between two elevation/color values will be a blend of the two bounding colors if the Blend Colors
Between Elevation Values option is checked. For example, if an elevation of 500 meters was set to black and
an elevation of 1000 meters was set to white, an elevation of 750 meters would be colored a medium shade of
gray. Any elevations below the minimum specified elevation will use the same color as the minimum
elevation. The reverse is true for any elevations over the maximum elevation. If the blend colors option is not
checked, any elevation between two elevation values will be set to the color associated with the lower of the
elevation values.
If you would like the elevation values selected to scale to the elevation range of the currently loaded data
rather than stay at fixed elevation values, check the Scale Shader to Loaded Elevation Values. This will make
your shader behave similar to most of the built-in shaders, like the Atlas or Color Ramp shaders. For example,
if you check this option and specify that an elevation of 0 meters is blue and 1 meter is red, and the actual
loaded data has a range of 100 meters to 500 meters, then 100 meters will be blue and 500 meters will be red,
with the values gradually shaded in between (if you have the blend colors option checked).
