🔥 Boost Your Blender Grooming Workflow with GroomFlow Pro!

GroomFlow Pro is an advanced, guide-driven grooming add-on for Blender designed for professional character artists. Say goodbye to heavy viewport lagging and messy root alignment. Generate dense, production-ready hair and fur effortlessly using a clean, non-destructive pipeline.

🚀 Key Features

• Guide-Based Strand Generation
  Create dense, high-quality hair strands from lightweight guide curves. Maximize visual fidelity without the performance limitations of traditional systems.

• Surface-Locked Distribution (BVHTree-Powered)
  No more floating roots or mesh clipping! Our continuous surface projection system perfectly snaps every strand root directly onto high-curvature areas like eyebrows, eyelashes, and beards.

• Optimized & Non-Destructive Workflow
  Keep your guide curves completely separate from the generated output. Enjoy a clean, mirror-professional pipeline ideal for character hair, fur, and Unreal Engine groom preparation.

🆕 What's New in v1.8.2 (Hotfix)

• NEW: Trim by Mask - children outside the mask are deleted
• Guides are only born where the mask allows, but their children scatter around them, and at a wide Radius that scatter reaches past the painted area and grows hair on bare skin.
• Trim by Mask (Children > Root Distribution) reads each child root back against the very mask the guides were generated from - the vertex group or the texture mask - and deletes the children that fall outside it.
• Mask Threshold is its own value, separate from the guide generator's Weight Threshold, so the children can be trimmed tighter or looser than the guides. It is read against the strongest value the mask actually holds, so 1.0 means "only where the mask is at its strongest" even on a mask that never reaches a clean 1.0.
• It costs nothing: the mask is sampled from the polygon each root already reported to the surface snap, so there is not one extra query. With fewer strands left to write, a trimmed groom builds faster - measured at 300 guides x 200 children, 181 ms down to 94 ms.
• Fix: Children stretched longer than their guide as Radius went up
• The root correction that puts a child on the skin was faded out toward the tip, so the root was pulled onto the surface while the tip stayed where it was - the strand was stretched by however far its root had to travel. That distance grows with Radius on anything curved: measured on a sphere, children reached 1.40x the guide's length at Radius 0.2 and 2.74x at 0.8, a spray of over-long strands.
• The correction now moves the whole strand at once, so shape and length are kept exactly - 1.00x at every Radius.
• Fix: Children floating off the mesh at a small Radius
• With the children Radius at about 0.015 or below, some children's roots sat above the skin instead of on it.
• Each child's root offset is now kept flat along the surface, so the root starts on the skin. Above the root, that correction fades out toward the tip, so there is no kink at the base.
• Fixed in both the GPU and CPU children paths.
