Another week another Unreal Engine release, this time 4.12 Preview 4. Once again this is a preview release, so don’t expect to use it in production work and expect bugs. The biggest feature of this release is a preview of VR Mode announced back during GDC. This enables you to place and move actors in the editor while using a VR headset, currently Vive and Oculus Rift are supported.
Of course there are a host of fixes in this release as well:
