BambuStudio 1.9.1+ Setup: A single posterized_model.obj file will download. Drag it directly into BambuStudio. Because it uses embedded Vertex Colors, BambuStudio will automatically detect the colors and show a color-to-AMS mapping dialog — assign each color slot to the matching filament in your AMS. The Transition Layer column above is your reference for manual filament swaps without AMS.
