Ambulance Bay Hatching Decal

Flat forecourt marking decal under 0.02m thick spanning the full 2m module, yellow diagonal keep-clear hatching with a knob for plain hatch, bay side line, or bay end bar so a full bay is laid from copies.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
