LU Toolbox's metallic table also has colors the client's Materials.xml types shinyPlastic, such as 131, the grey of many baseplates, so whole baseplates went into S88_Metal_Model. Metal now comes from the Materials.xml types (shinySteel) and the settings' colors only; the table still gives colors. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
