Here are some USD Assets and Scenes for free to use for any purpose. Its setup with lights and shaders for Arnold renderer in GafferHQ. I will update the dropbox folder in the future with other render engine setups like CyclesX, Karma, Omniverse or Unreal5.

in this examples, it used the gaffer instancer and Arnold fog volume shader which quite fast on the GPU.
Models and Textures are selfmade and HDR is used from iHDRI.com
