Enemy Spawn Gate
The enemy spawn point of a tower-defense map: a pointed arch of dark stone, rusted iron or lashed timber with horned tops and glowing runes, filled with a swirling vortex, on a cracked slab with braziers either side. The opening faces +Z (enemies walk out toward +Z). The part named vortex spins about z (userData.tick, Loop clip baked); vortex, cracks, runes and fires glow at night.

Use it
Code for the specimen as it is set up above; it follows your knobs.
import { createAsset } from 'https://gaitkit.com/cdn/enemy-spawn-gate.mjs';
const enemySpawnGate = createAsset();
scene.add(enemySpawnGate); // rests on y = 0, front faces +Zimport { useMemo } from 'react';
import { createAsset } from 'https://gaitkit.com/cdn/enemy-spawn-gate.mjs';
export function EnemySpawnGate() {
const model = useMemo(() => createAsset(), []);
return <primitive object={model} />;
}# Import enemy-spawn-gate.glb (download below). Moving parts are separate nodes, pivoted on their hinge.
add_child(preload("res://enemy-spawn-gate.glb").instantiate())// Import enemy-spawn-gate.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": "enemy-spawn-gate", "want": "default look" })
then place the result.
