mip mapping terrain detail textures

Does anyone know how to do this, or does anyone have a shader that can do this?
My terrain looks ok until i get to the top of a hill, where I can see right across the map, and . . . IT BURNS MY EYES!!! thanks in advance

Put a second image (detail map)into your terrain then write in main something like
var detail_size = 4; , adjust as needed.

You probably already found this in the manual:

bmap_to_mipmap(BMAP*)

cheers

btw soz i am a complete shader noob, thats why i havent got a clue.

solved da problem now thanks
