Epic Games CTO Kim Libreri announced on the Google I/O stage support for Daydream to Unreal Engine 4. Daydream integration is available now on GitHub (login required), and it's coming to the binary tools in the full Unreal Engine 4.12 launch, which is on track for release on June 1, 2016.

Here's what Kim had to say: "At Epic our mission is to give developers the very best tools for building immersive and visually impressive experiences with great performance on every platform we support. We have been creating VR experiences for many years now that not only push visual fidelity but what’s possible in terms of input, interaction, characters and gameplay mechanics

"Every project we work on extends the capabilities of Unreal Engine, and we pass these improvements to developers on a daily basis. Today we’re proud to be part of this new chapter in VR history."
