The biggest thing, of course, is the new Chaos physics and destruction system, but there’s more to it. The update brings the Skin Weight Profile system, the new Unreal Insights Tool (Early Access), and a number of virtual production upgrades. What is more, it features significant improvements to the Niagara workflow, many editor updates, HoloLens 2 support, and more.
You can find the full list of upcoming changes in the new build in the 4.23 Preview 1 forum thread. Please note that the preview, of course, is not production-ready.
To get Unreal Engine 4.23 Preview 1, head to the Library section on the launcher, select “Add Versions” and choose 4.23 Preview 1.
