And I'm back! After studying everything Houdini (and ZBrush) for 100 days to learn Solaris, procedural geometry, grooming, and a bit of fluid VFX I felt ready to try grooming a head I had sculpted.
Using DenisZen's technique of grouping polys (in ZBrush) before importing, I was able to attack zones one at a time. What a great way to start as compared to painting attributes for zones. My scalp was one zone, but my eyebrows and lashes were different–a beginners effort. I realized that eyelids just don't have enough smooth topology to paint eyelashes, so I took a new approach starting this week. I draw a curve on the polygroup for the eyelid, use a VOP node to get the relative bounding box and add a Channel Ramp to control an EyelashLength attribute that is BindExported from the VOP.
Taking DenisZen's advice from RocketGrooming, I made an eyelashes node that places hairs along a grid that has been MatchSized and PathDeformed to match the Drawn Curve (which is Resampled and Smoothed). My EyelashLength attribute can now control the profile of the lashes to look lofty on the outer edge, shorter all around, or even patchy. Thank you DenisZen for the reminder to always share knowledge in your tutorials!
Moving into Solaris, I discovered the KarmaHairProcedural...a 19.5 node that replaces the experience of using the shelf "add fur" set up, but in Solaris. After many red exclamation marks, I got it to work, showing hair while rendering in real time. There is only one HairProcedural tutorial on YouTube called "Wheat Fields using Karma" by Jason Slabber. Crucial info is included here to using MaterialX yielding different hair strand colours. Houdini has the best information in their documentation, allowing you to open a demo file to see a furry Torus.
I checked out the Patreon of JesusFC to get that crucial knowledge of grooming tutorials, but to date I feel like DenisZen is the ONLY one using hair for scalps and not bears and lions and dogs. But now, so am I. Thanks for being the inspiration to get a hobbyist grinding from "meager ogre" to "mediocre"!! I LOVE hair grooming now...but I still steer clear from GuideGroom nodes :D

Thank you for this awesome tutorial. Very good insights and I'll be going through it a few more times.
There are two nodes that are included with your 'allHere' setup that are unfortunately missing:
'DViz' and 'smartViz'
These show up in the network, they have adjustable parameters, but they unfortunately have no contents (and no effect in the graph).
You made pretty good description for the 'DViz' node, and I'm going to try and recreate it.
If possible, it would be awesome if you could include those two nodes in the 'allHere' graph
Thank you so much for sharing your knowledge!
Gratefully,
Lars
