noise modifier for geometry?
I am toooo used to max i know.
I have a flat desert plain, and I want to rough it up a bit, and I don't want to use displacement mapping, too calc intensive.
is there a way just to add a noise modifier to the geometry to rough it up a bit?
thanks.
Adam.

global proc displaceCVs(float $minVal, float $maxVal)
{
$sel = `ls -sl`;
$Udiv = `getAttr $sel".spansU"`;
$Vdiv = `getAttr $sel".spansV"`;
//loop through the CVs and add random amounts to their y direction.
$i = 0;
for($i = 0; $i < $Udiv; $i++)
{
$j = 0;
for($j = 0; $j < $Vdiv; $j++)
{
select -r $sel.cv[$i][$j];
float $displace = `rand $minVal $maxVal`;
xform -r -t 0 $displace 0 ;
}
}
}
If you've got a poly surface it's the same idea.
