Example: Road Decal Management

local decals = require('editor/tech/roadArchitect/decals')

-- Create decals for a road after geometry is computed
decals.createDecals(road)

-- When road geometry changes, mark dirty then update
decals.setDecalsDirty(road)
decals.tryUpdateDecals(road)

-- Remove decals when deleting a road
decals.removeDecals(road)

-- Remove all decals from all roads (e.g., on level unload)
decals.removeAllDecals(roads)

-- Available material presets for lane markings
local mats = decals.getDecalMaterials()
-- Includes: solid_white, dashed_white, solid_yellow, dashed_yellow, etc.

-- Decal types placed per-lane:
-- Edge lines - along lane outer boundaries
-- Center lines - between opposing traffic lanes
-- Lane arrows - directional indicators at intersections
-- Surface patches - textured overlays on road surface

Notes

Decals are Torque DecalRoad objects positioned along render data polylines
Materials reference pre-existing texture assets in the game
Decal placement follows the road's render data lateral offsets
