'Evening all . . . :^) I need some advise: I'm having a problem with-in the terrian editor? OK, I create a terrain / go into the terrain edit mode / I select "Reset" to flatten / select picture & bring up the bitmap. ( Image posted ) The problem I seem to be having is, the horizontal surface of the terrain is not flat or smooth, like in the bitmap image used for the terrain? I'm sure I'm missing something, but I've searched the manual with no results. I've also tried several different filters & functions, but I couldn't get the terrain flat. If some kind & experienced Vue 4.06 wizard would throw some light on this subject, I'd gladly throw a nice cold brew your way! :^) Thanks in advance for any help & have a good one . . . Mark.
