XGen实用噪波修改器表达式

第一层噪波：

$nonStrayValue = 0.0000;#0.0,1.0

$strayValue = 1.0000;#0.0,1.0

$percent = 80.0000;#0.0,100.0

$stray = hash($id) <= $percent/100.0 ? $strayValue : $nonStrayValue;

$stray

第二层噪波：

$hi =1.0000;

$lo =0.5525;

$contrast =0.6030;

$freq =25.0000; #.1,30

smoothstep(noise($P*$freq), $lo, $hi) -> contrast($contrast)

第三层噪波：

$hi =0.1625;

$lo =0.4675;

$contrast =0.5000;

$freq =25.0000; #.1,30

smoothstep(noise($P*$freq), $lo, $hi) -> contrast($contrast)
