The Xrd developers state they edited normals on every major feature and hand-crafted face normals, and did not use normal maps. A Japanese ASW lecture deck (published 2025-07-30; glossed here) names three control methods: place vertices so automatic normals come out right, transfer normals from another mesh, and set normals by hand (reserved for faces; whole-body is called impractical), and lists limits: normals rotate with bones, no subdivision surfaces, extra care with hull outlines. Blender documents Normal Edit (with Max Angle to avoid shading artefacts, described as useful for toon-like shading) and Data Transfer (custom normals).

Curator qualifications: Hand-edited normals on major features instead of normal maps (Xrd); three control methods in a Japanese ASW lecture (glossed).
