Feature Highlights

Grass Rendering and Procedural Foliage Systems We've optimized our Grass Systems for use with large open worlds. Use it to produce huge amounts of grass and ground cover with temporal LOD cross-fading. We're also releasing an experimental preview of the procedural foliage system we used to paint foliage across our GDC 2015 Kite Demo.

Plugins Available in Marketplace We've partnered with Allegorithmic to provide our first plugin available in Marketplace. Download the plugin today, and look for more plugins from select partners in the future!

Post Processing Enhancements and Tools Major increase in accuracy of our Motion Blur, including morph target animations that can now generate motion blur. We've also updated our depth of field to be more physically-based, as well as added a new Tone Mapper to achieve more filmic look.

Network Replays "Scrubbable" network replays with rewind support and live time scrubbing.

Asset Size Mapper Visualize the memory footprint of game assets in an interactive tree map UI.
