grass problem for my terrain

hi all I love this program , its great to make yourself games, but I think it has a small but important "bug" when I tried to draw grass ( I know detail distance .mark it 250 ) but when I paint grass its "view" follows the player , other word it appears only the players distance, and I think its

I know the way to fix this is edit terrain script , can you help me?

Is it because your grass have billboarding enabled? When you create, or edit your grass texture on the terrain, you can untick billboarding.
