Nuke Stage uses the Hydra rendering system from OpenUSD, allowing high-performance 3D rendering through interchangeable delegates. Hydra delegates are broadly supported by tools like Nuke, Katana, Maya, Houdini, and many others.
Nuke Stage does not support rendering from Unreal Engine, but it works well alongside it. Unreal can export to USD, which Nuke Stage supports natively.
Additionally, Nuke’s UnrealReader node lets you bring render passes from Unreal Engine directly into Nuke, making it easy to use Unreal’s high-quality rendering path to build and refine your virtual environment.
