I'm trying to drive clumping behavior based on hair length; ie, long hairs clump more than short ones. There's a great example in the help files using this code:
$a =$cLength;
$max =7.00;
clamp($a,0,$max)
However, this throws an error, as it's using $cLength, which (according to the help docs) isn't available for Xgen Interactive groom, though the $cWidth parameter is.
"$cLength The final, computed length of the current primitive.
$cWidth The final, computed width of the current primitive. Note: Supported by Interactive Grooming Splines. "
Double checked with support, and right now, there's no way to drive anything based on the length of the IGS primitive. However, it works fine in regular XGEN.
Please please let us at this variable.
