The release of Unreal Engine 4.18 is rapidly approaching, with many fantastic updates for you to try out. The first Preview build is now available on the Epic Games launcher, so you can experiment with brand new changes, such as volumetric lightmaps, enhanced static skylight directionality, major clothing tool upgrades, the revamped Physics Asset Editor and Media Framework 3.0. In addition, you can access improved support for both Google's ARCore and Apple's ARKit. The desktop forward renderer on iOS, used in the Wingnut AR demo at WWDC 2017, is now available as well (recommended for devices with an A10 or later processor running iOS 10.3 or newer).
To get Unreal Engine 4.18 Preview 1, head to the Library section on the launcher, select “Add Versions” and choose 4.18 Preview 1.
A more detailed list of upcoming changes in the build has been posted on our forums by Stephen Ellis. Please keep in mind that Preview releases are intended only to provide a sample of what is going to be released in the update and are not production-ready. We recommend waiting for the full release of 4.18 before updating your projects to the new engine version.
