YUMI

What's new in this version:

Real-time ray tracing (now available in Early Access):
- Selectively ray trace just the passes that benefit from it  to achieve subtle, accurate effects that contribute to the realism of your scene, like reflections from off-screen objects, soft shadows from area lights, and ambient occlusion—at blazingly fast speeds.

Performance enhancements:
- We’ve completely rewritten mesh drawing to significantly improve draw performance. We’ve also licensed Molecular Matters’ Live++ for all developers to use on their Unreal Engine projects. In addition, we have dramatically reduced build times, enabling much faster C++ iterations.

Virtual production tools:
- New and enhanced tools designed to facilitate virtual production and live entertainment include a new UI for real-time compositing; simultaneous multi-user editing; more efficient multi-display rendering; and support for additional media I/O formats.

Microsoft HoloLens remote streaming support:
- You can now wirelessly stream your Unreal applications from a Windows-based PC to Microsoft HoloLens in real time, making it easy to rapidly test, iterate, and experiment while developing HoloLens applications. We’ll also be fully supporting HoloLens 2 starting in May 2019.
