# V15.07.03

Hair Tube Builder Phase 3 changes + bug fixes

Release Date - 10/21/2026

## Hair Tube Builder

### **New Features**

* **Bend Points** lets you bend strands by dragging viewport dots. Add, slide, or remove interior dots along a strand. This is not a ‘CV move tool’. 
  * **Bend Points** reshapes a strand through control dots placed along its length. Dragging a dot calculates a weighted adjustment across the underlying curve’s CVs: nearby CVs respond more strongly, while others respond less according to the dot arrangement and curve structure. This produces a distributed bend rather than translating one CV with Maya’s Move tool.

    Adding, sliding or removing interior dots changes where you control the bend. The dots are editing handles, not individual CVs, and a drag can affect the curve between neighboring dots.

* **Length (%)** **Mode** sets strand length as a percentage of its full curve length. You can now switch modes using the (%) button beside the Length slider. The **Randomizer** now includes a separate Length (%) row.

* **Root Markers** now use temporary viewport drawing dots instead of geometry spheres to reduce scene size and increase speed.

### Improvements

* **Quick Handles** section added and it's located above the Strand Editor tabs. One handle type can be displayed at a time. You no longer need to open the Scene Presets just to change the Handle colors.&#x20;

* Profile, Scale, Twist, and Spiral **Handles** now have more distinctive viewport shapes.&#x20;

* Handles (Scale/Twist/Spiral Radius/Spiral Turns) hotkey changes:
  * LMB + Drag = Edit value
  * MMB = Slide
  * Profile Handles, when LMB + Drag on a handle, it can now scale the selected profile.
* On the Profile Curve CV Editor, added in the **Select**, **Crease**, and **UV** highlight controls so you can directly set the visibiilty and colors of each highlight. You no longer need to open the Scene Presets just to change the highlight colors.&#x20;

* Due to the above changes, Profile highlight section and the Handle settings in the Scene Presets window (Introduced in V15.07.01) are now removed.
* Removed section headers inside the Strand Editor tabs for clearer readability.
* Selecting multiple strands now displays “Select only one strand to edit” inside the CV canvas, the old cyan warning banner that shows is now removed.
* Edge highlights will now update more smoothly on geometry shape or transform changes.
* Required plugins (lookdevKit.dll, xgtc\_plugins.py) will now automatically load when HTB opens. Added checks and clearer warnings for missing required plug-ins or HTB nodes.

### Fixes

* Profile CV Edit will now protect the first CV (.cv\[0]) and prevent deletion that would leave fewer than 3 CVs.
* Ctrl + LMB now deselects CVs instead of deleting them. To delete CVs, use the **Delete key** on the keyboard or right-click the canvas and choose Delete Selected CVs to remove CVs.
* Crease, UV, and selected CV highlights will now follow changes to the tube shape without the previous lag.
* Clean Selected Curves will now remove the leftover Loft Degree attribute introduced in V15.07.01, so cleaned curves can be used to create new strands.
* Re-worked the Vertex/Gradient color logic, copy/pasting will not affect existing coloring of a strand anymore.
* On Linux/VM machines, Handles may not register the mouse button release callback correctly, causing them to appear sticky. This is now fixed for all Handles except Profile Handle.

### Updating Older Scenes

Install the current version by dragging the `Maya_DragDrop_Installer.py` into Maya viewport, open your scene, launch Hair Tube Builder, select a strand and run **Update to Current**.

## Interactive Curve Tools

### Fixes

* Sculpt: Corrected a brush coordinate fallback used when Maya cannot provide the viewport height. The reported Maya crash has not yet been confirmed as resolved.&#x20;
