Randon Value

$randmin = 0.001; #0.000,0.050 $randMax = 0.003; #0.000,0.050 $seed = 154.0000; $randValue = rand($randmin,$randMax,$seed); $randValue

Randon by absolute Length ( a must for the cut modifier)

$randmin = 0.001; #0.000,0.050 $randMax = 0.003; #0.000,0.050 $seed = 154.0000; $randValue = rand($randmin,$randMax,$seed); $randValue*@cLength

Mask * Density

$mask=map('${DESC}/paintmaps/Mask');#3dpaint,50.0 $density=map('${DESC}/paintmaps/Density');#3dpaint,50.0 $mask*$density

Percentage

$percentage = 0.1500; #0.000,1.000 $randValue = rand(0,1)<$percentage; $randValue

Melanin Color

$percentStray=51;#0,100 $a=rand() < $percentStray/100.0 ? 1 : 0; $MelaninA=0.15; $MelaninB=0.65; $b=$a<=0.10 ? $MelaninA:$MelaninB; $b

Complex Noise

$hi =1.9800;#01.0,10.0 $lo =0.3100;#0.0,1.0 $contrast =0.2450; $freq =1.9900; #.1,30 $noise=fit((smoothstep(noise($Prefg*$freq), $lo, $hi) -> contrast($contrast)), 0, 1, 0, 100); $p=map('${DESC}/paintmaps/NoiseMask');#3dpaint,30.0 $mult=1.4050;#0.00,10.00 $p*$t*$noise +(1 -$p)*($cLength+($mult-$cLength))

Ramp per length ( $t not absolute length)

$ramp=linearstep($t,0.0,1); $ramp

Random per length ( $t )

$randmin = 0.7000; #0.000,0.050 $randMax = 1.0000; #0.000,0.050 $seed = 154.0000; $randValue = rand($randmin,$randMax,$seed); $value = linearstep($randValue,0,1); $value

Displacement Re Fit

$a=disp(); $min=0.1700; $max=1.0000;#0.0,5.0 fit($a, 0,1, $min, $max*2)

Flyaway percentage

By Mustafa Mohsen

$FlyawayPercentage =0;#0,100 $FlyawayAmount=0.0000;#0.00,1.00 $FlyawayAmountMap=map('${DESC}/paintmaps/FlyawayAmount_map');#3dpaint,10.0 (rand() > $FlyawayPercentage/100.0 ? 1 : 0)+$FlyawayAmount+$FlyawayAmountMap

Operation by length ( Change * for any of + - / when needed)

$mult = 9.40141;#0.00,10.00 $mult*$cLength
