 ### Beyond the Basics
 
 I recommend reading through the USD tutorials here [https://graphics.pixar.com/usd/release/tut\_usd\_tutorials.html](https://graphics.pixar.com/usd/release/tut_usd_tutorials.html), and experimenting in Blender and Nvidia USD Composer with creating or importing scenes and exporting to usda format files.
 
 Note: Blender does not support references:
