ADE ground line

my ground line is only visible when the plane is close to the line. Too far the intensity of the line is at 50% and improves as the plane approaches the line. Can you tell me where is my mistake or have a solution ?

ADE Version:
Application 01.76.6715.14291
Engine 04.75.6712.18978

Thank you & kind regards

You could try removing (or adding) mipmaps to the texture, to see if that helps. Some video cards react differently to them.
