Passed the validator: real scale, rests on y = 0, front faces +Z, deterministic.

Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript

import { createAsset } from 'https://gaitkit.com/cdn/roof-piece.mjs';

const roofPiece = createAsset();
scene.add(roofPiece);                      // rests on y = 0, front faces +Z

JSX

import { useMemo } from 'react';
import { createAsset } from 'https://gaitkit.com/cdn/roof-piece.mjs';

export function RoofPiece() {
  const model = useMemo(() => createAsset(), []);
  return <primitive object={model} />;
}

GDScript

# Import roof-piece.glb (download below). It is a static mesh, one material per colour.
add_child(preload("res://roof-piece.glb").instantiate())

// Import roof-piece.glb with glTFast (com.unity.cloud.gltfast).
// Drop it in the scene: 1 unit = 1 metre, +Z is its front.

Use the gaitkit MCP server: get_variant({ "id": "roof-piece", "want": "default look" })
then place the result.

Knobs

Knob	Type	Values	Default	What it does
`style`	choice	`dungeon` `scifi` `house`	`dungeon`	Shared by every Modular Level Kit piece: dungeon (coursed stone blocks, iron and oak), scifi (bolted panels, trims and glowing light strips), house (plaster over wood or brick wainscot, timber trim). Use one value across a level.
`colorway`	choice	`classic` `dark` `warm`	`classic`	Palette within the style, shared across the kit: classic (dungeon grey granite, scifi light grey with orange, house cream plaster and brown wood), dark (basalt, gunmetal with yellow, white plaster with black timber), warm (sandstone, beige retro with teal, ochre plaster with honey wood and brick).
`piece`	choice	`slope` `ridge` `flat` `gable`	`slope`	slope (lean-to, eave at +Z, high edge at -Z), ridge (gable roof over one cell), flat (roof deck with a +Z parapet), gable (triangular end wall under a slope, runs along X with its low end at +X).
`eaves`	toggle	on / off	`true`	Slopes and ridges overhang the walls by 0.3 m with a fascia, gutter or light trim and a wall plate under them; on flat it raises the parapet; the gable follows the same roof line. Off: the roof stops flush at the wall line.
`wear`	range	0 to 1, step 0.1	`0.2`	0 = new; higher adds moss and slipped or missing slates and tiles, rust streaks on metal panels, stains.
