Mipmap problem

[CZorg]

Is there a way to increase the LOD of a specific surface?
The reason I wonder is because the mipmaps makes my lava material look stupid in a distance further than just a couple of feets ahead of the main character.

Here's an image to show what I'm talking about


And for those who don't know what mipmaps are: http://en.wikipedia.org/wiki/Mipmap

Try to open the terrain properties and thick "morph enabled" box.

That didn't make any difference, atleast from what I saw... But thanks anyways!
