Unreal Engine 4.15 Preview 1 was released a few days back (sorry, machine failure took me offline for a few days) with a taste of what’s to come in the upcoming 4.15 release. A restructuring of the C++ code layout has resulted in a measured 50% improvement in compilation speeds, a new reroute system for material blueprints should certainly help with readability and perhaps the biggest announcement is the recently introduced Blueprint to C++ system is now out of beta and considered production ready.
Details from the announcement blog:
We've changed the build process to an 'include what you use' model, where every header includes other headers it needs, rather than every source file. With this change we've measured the engine compiling up to 50% faster than before.
With reroute nodes now available for use in the Material Editor, say bye-bye to spaghetti wires!
The Blueprint to C++ cooking feature is no longer experimental and is now production-ready.
We've also added some new experimental features such as Content Hot Reloading and Monoscopic Far Feld Rendering for mobile VR. We are excited to share the features with you and hear your feedback!
