RadiantUI

CEF Based Web Browser Integration into Unreal Engine 4

Released under the MIT license.

Key Features:

Render HTML/CSS/JavaScript to any surface/material in the game.
No C++ coding required, everything is done through blueprints and components.
Automatic Input handling: Walk up to any WebActor and use the mouse and keyboard automatically (Doom3 style interfaces).
Supports non-flat surfaces: You can map a WebActor onto any mesh and still interact with it (Curved computer screens etc).
Networked gameplay support: Multiple players can interact with the same WebActor and see the same output.

UE version 4.5 removed the ability to do non-rectangular hit-testing. Currently any Radiant WebView HUD Elements that have hit testing enabled consume input from the entire screen. This probably could be fixed by adjusting the slate widgets.
