Hello, the material of this topographic surface is grass (which is obviously green), although, in the 3D view it shows like this do you know whats going wrong???
Not showing the right colour of the material
A material has two tabs related to colour of your material, Graphics and Appearance.
The settings in Graphics are used when view is in Shaded & Consistent Color mode. The settings in Appearance are use in Realistic mode. The standard grass material of Autodesk contains black and green pixels, resulting in a dark/black looking material when looking from far distance in realistic mode
