mr Proxies

In this tutorial, you will learn how to use mr Proxy objects to create a scene of a forest that, despite its large size, can render quickly.

You will convert trees to mr Proxy format, then give each proxy a material you saved in a material library. Finally, you will use the Object Paint feature to instance the proxies multiple times and distribute them across the scene.

In this tutorial, you will learn how to:

- Save materials to a material library
- Save objects in mr Proxy file format
- Create mr Proxies and associate them with imported proxy files
- Add materials to mr Proxies
- Use Object Paint to instance and distribute mr Proxies in a scene
