RenderManStudio_Layout_v01.hip
This scene is where the layout magic happens.
The $HIP/usd/Assembly/RenderManStudio_Assembly_v01.usda file is referenced and then using both the setvariant and edit nodes, the assets are laid out and the scene formed.
Feel free to drop a camera here as well, but don't forget to add a layerbreak node if you don't want that layout camera to be saved
