# PMTilesOverlay

class in `3d-tiles-renderer/three/plugins`, extends `MVTOverlay`

```js
import { PMTilesOverlay } from '3d-tiles-renderer/three/plugins';
```

Overlay that renders PMTiles vector or raster data on top of 3D tile geometry.
Projection and zoom levels are read automatically from the PMTiles archive header.

> **Note:** Direct use of PMTiles requires range requests, which are not automatically cached
by the browser. It's recommended to implement a service worker to cache response content
to save bandwidth.
