Once installed, you can find this add-on in Blender's 3D Viewport's N Panel, under the Hair tab.

Installation

  1. Move the comb_utilities directory inside Blender's \scripts\addons\ directory, e.g. C:\Programs\blender\2.93\scripts\addons\.

This is a Windows-only add-on, because you also need to install AutoIt to run the additional scripts that the add-on uses to control the mouse cursor. The add-on assumes that you've installed AutoIt with all of the default options.

You will also need to set up several Blender keyboard shortcuts to properly use this:

  • 3D View → 3D View (Global) keyboard shortcut so that Shift Ctrl ] gets assigned to rhhc.rotate_add_plus_deselect. (This is required for the Auto Comb Helicopter Hair script.)
  • 3D View → 3D View (Global) keyboard shortcut so that Shift Ctrl [ gets assigned to rhhc.done_combing. (This is required for the Comb Selected Hair Down script -- it's the only way that we know whether we need to toggle off the X-Ray.)
  • 3D View → 3D View (Global) keyboard shortcut so that Alt Numpad 8 gets assigned to rhhc.comb_selected_hair_up. (This makes it easier for the user to repeatedly comb hair downward.)
  • 3D View → 3D View (Global) keyboard shortcut so that Alt Numpad 2 gets assigned to rhhc.comb_selected_hair_down. (This makes it easier for the user to repeatedly comb hair downward.)
  • 3D View → 3D View (Global) keyboard shortcut so that Alt Numpad 4 gets assigned to rhhc.comb_selected_hair_left. (This makes it easier for the user to repeatedly comb hair to the right.)
  • 3D View → 3D View (Global) keyboard shortcut so that Alt Numpad 6 gets assigned to rhhc.comb_selected_hair_right. (This makes it easier for the user to repeatedly comb hair to the right.)
