Previewing the Surface Map

The Surface Map’s render contains technical information used for calculating shadows and lighting. With some manipulation, this render can be very useful for problem-solving surface details and rigging.

The standard surface map renders a mapping that displays the X-position in fields in the red channel, the Y-position in fields in the green channel and the Z-position (elevation) in fields in the blue channel. The X and Y (red and green) coordinates are calculated automatically, but the Z values (blue channel) are provided by the defined ranges in the Surface Map and the attached Height Maps.
