… skin maps Babylon 4.2's glTF serializer keys each exported image by the Babylon texture name; when two distinct textures share a name the second one's glTF texture entry aliases to the first image. DCL avatars reuse the name AvatarSkin_MAT (Base Color) across body parts that carry different image data (the head a clean 1024 skin map, the body a darker 2048 one), so the head inherited the body's map and rendered dark, feature-placeholder texels around the nose and eyes. Make every texture name unique for the duration of the export, then restore so the live scene is untouched. Verified: head now references its own 1024 image, nose dark-pixel fraction 9 percent to 0 percent in a Blender VRM-addon import. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
