Making custom hair for BG3 with Hair Tool

Prerequisites:

BG3 Modder’s Multitool
LSLib
Blender 3.6 or 4.0
GR2 import/export addon for Blender
Hair Tool addon and preset library
VSCode
UUID addon for VSCode
Em’s Quick Hair Template or any other hair template

This video covers steps 1 through 13 below.

Steps:

Load environment (head, body if desired)
Load Hair Tool preset, flip 180 degrees and place on the head
Make some edits to the preset
Finalize hair to turn preset into mesh
Load BG3 hair texture and apply to the hair
Manually fix the UVs by X-flipping, then scaling down to the correct size
Find similar vanilla hair and load it into Blender
Parent custom hair to vanilla armature, add armature modifier
Transfer auto-snapping weights from vanilla hair to custom hair
Rename object data name to match vanilla hair
Reset vertex paint to black
Paint blue highlights, blur out
Apply all transforms, export as .dae
Using LSLib, conform to vanilla hair, then export as .GR2
Hotload into game as a replacer, make any necessary changes to the mesh
Set up quick template for the custom hair
After seeing it in game, change hairpreset, scalp, and material IDs if needed
Done!
