1. Scale Sora to 1.0, match custom model to that scale
2. Match custom model's mesh to Sora's as closely as possible. With bones being painted perfectly, THIS is the most important step now.
3. Use Cats Blender Plugin and press the big "Fix Model" button to normalize the custom model's bone names.
4. Click on Custom Model's armature and head to scripting. Use my "KHModelScript" to rename those normalized bones into KH Bones.
5. Click on Custom Model's armature, then Sora's armature, and use Tails's Tekken script to match KH3's armature to the custom model's armature one-to-one.
6. Click on Custom Model's Mesh, then Sora's Armature, and press ctrl-P. Parent the mesh to KH3 Sora with "Armature Deform"
7. If the KH3 model has animations, play them and look for unpainted mesh. Paint where necessary.
8. Export and prepare inside UE4 like usual (edited)
