Aurora: Autodesk's Open-Source Real-Time Path Tracing Renderer

The renderer supports rapid design iteration in a viewport and can be used within the USD ecosystem.

Check out Aurora, Autodesk's open-source real-time path tracing renderer that relies on GPU hardware accelerated raytracing. Released by the team back in July, Aurora is an interactive renderer that supports rapid design iteration in a viewport and comes with HdAurora, a USD Hydra render delegate that allows it to be used within the USD ecosystem. According to the developers, the renderer was created to "make the design and review cycle faster" and aims to "be functional across hardware vendors and operating systems".


  • Path tracing and the global effects that come with it: soft shadows, reflections, refractions, bounced light, and more.
  • Interactive performance for complex scenes, using hardware ray tracing in modern GPUs.
  • Autodesk Standard Surface materials defined with MaterialX documents, which can represent a wide variety of real-world materials with physically-based shading. Also, independent layers of materials are supported, which can be used to implement decals.
  • Environment lighting with a wrap-around lat-long image.
  • Triangle geometry with object instancing.
  • A USD Hydra render delegate (HdAurora) and standalone sample application (Plasma).
