Glass Marble

Glass marble, 1.6m: a clear glass sphere with a twisted coloured cat's-eye ribbon inside and a bright window highlight; a swirl knob (blue / red / green / amber). A rolling boulder for the bug world.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
