Create Better Hair and Fur in Houdini
Creating convincing hair, fur, feathers, or stylized grooms in Houdini can be challenging without the right workflow. While Houdini already includes powerful grooming tools, handling large numbers of guides efficiently often requires additional utilities that speed up repetitive tasks.
GroomBear Fx is designed to make the grooming process faster, smoother, and more interactive. With a collection of specialized brushes and guide editing tools, artists can shape hairstyles, animal fur, feathers, and other strand-based assets with much greater control while staying inside Houdini.
What is GroomBear Fx?
GroomBear Fx is a professional grooming toolkit for SideFX Houdini that allows artists to create, edit, and manage grooming guides and cards more efficiently.
Instead of manually adjusting thousands of guides one by one, GroomBear Fx provides a complete set of interactive brushes that make styling feel much more natural. Whether you’re creating realistic character hair, animal fur, feathers, or stylized hairstyles, the toolkit helps you work faster while maintaining precise artistic control.
For example, a character artist can quickly comb long hair into shape, scatter guides across a surface, cut unwanted strands, paint masks for selective editing, and finally convert guides into hair cards for game-ready assets—all within the same workflow.
This streamlined approach saves time, reduces repetitive work, and produces cleaner, more consistent grooming results.

Tips for Better Results
While GroomBear Fx provides artists with a variety of tools to create their grooming projects, it is also essential for artists to use the correct techniques with the available tools. Here are a few tips to help artists create their grooming projects more efficiently:
- Always begin with the overall shape of the groom.
- Use masking to isolate specific areas to edit.
- Smooth grooming guides regularly for the best results.
- Use clumping only lightly for grooming projects.
- Only convert grooming guides to grooming cards after finalizing the grooming project.
- Use multiple types of brushes to create natural looking hairstyles.
Final Thoughts
As one of the most detailed aspects of character creation, grooming assets are essential for character projects in Houdini. The inclusion of grooming tools within Houdini helps to create an overall more efficient production pipeline for character designers. However, GroomBear Fx takes this a step further by providing artists with additional tools and brushes to help them with grooming projects.
From creating realistic characters and animals to game-ready hair cards, GroomBear Fx allows artists to create their projects quickly and efficiently while maintaining full control over their grooming tools.
