Welcome


MoonRay is DreamWorks’ open-source, multi-award-winning, state-of-the-art production MCRT renderer, which has been used on feature films such as How to Train Your Dragon: The Hidden World, The Bad Guys, Puss In Boots: The Last Wish, the newest release, Ruby Gillman: Teenage Kraken, as well as future titles. MoonRay was developed at DreamWorks and is in continuous active development and includes an extensive library of production-tested, physically based materials, a USD Hydra render delegate, multi-machine and cloud rendering via the Arras distributed computation framework.

MoonRay is developed in-house and is maintained by DreamWorks Animation for all of their feature film production. Many thanks go to all of the engineers for building and delivering this state of the art MCRT renderer since the very beginning, and to DreamWorks Animation for continuing a long tradition of contributing back to the wider computer graphics community.
