The project for this week focuses on how to make grooms utilizing Houdini for hair generation. I utilized my concept for Purah's third form, the Primal Shoosuva as a reference to create a basic head sculpt, minus the horns, and went through two seperate tutorials to learn the rough process.

Base Sculpt
I used Arvid Schneider's 'How to Groom Hair & Fur in Houdini' tutorial for the majority of this process, going through the basics so I could run my own experiments and play with the different tool settings. For this part of the process, I didn't put much focus on the realism/reference of Smilodon's hair, but rather on understanding the process and what goes into making hair generation content. A real, "Make it exist first" workflow
This project was inspired by AVASCOT's Groom Shader as a base, specifically its ability to make realistic blends of hair throughout the same coat utilizing masks. Although this wasnt utilized in this portion of the experiment, I'll be making revisions in favor of this plugin.

Debugging
I knew this would be part of the process and something to keep in mind, but I find it really interesting. that you are still able to see tiny amounts of the skin through the fur. While looking through other hair card references for humans, I came upon this diagram from Mountain Dog Studios of their real-time hair breakdowns. If I am able to spawn hair within small areas and have the system react accordingly, I think this would help give more control and a fuller volume to the groom.
One of the biggest problems with this groom so far has been the inclusion of hair where I don't intend on it. This has been especially noticeable in the mouth with lots of hair growing into the lips. Even if the hair isnt long, the small dots don't disappear with adjustments to the base fur map.
