Hello Jeordanis.

I use Ornatrix since a while now, and even if I read the documentation several times, I still have difficulies to make clumps working correctly.

My main and recurring problem is, how to limit the clumps to the nearest hairs and prevent them to reach hairs which are at the other side of the world.

In my experiencen only the "Clumps From Guides" does the job successfuly, but the number of guide often not correspond to the number of clumps we want.
"Clump From external Clump Strands", works most of the time, but also lead to hairs travelling to far.
"Random mode" work only if we create a channel to separate the right and the left hairs of a head and don't prevent hairs to reach too far hairs.
And "Group mode" isn't really more efficient.

To illustrate this, I have made this simple scene where I use a perfectly sharp box noise to generate a lot of different groups using "Strand Data" node.
I set the clumps mode in "Strand Group", checked "Preserve Lenght" and "Attract to Closest Stem" and I was expecting to obtain one perfect clump for each group.

But as you can see in the attach video, even like this, it does'nt work.

Is there something I missed ?
