What"s New:

Unreal Engine 4.27 offers new features and enhancements for creators across all industries. In‑camera VFX goes next level with a slew of efficiency, quality, and ease-of-use improvements to lớn the virtual production toolphối, while other highlights include path tracing for stunning final images, out-of-the-box access khổng lồ Oodle và Bink, production-ready Pixel Streaming, and much more.

nDisplay enhancements

Applications that use multi-display rendering, including in‑camera VFX, are now much easier to lớn mix up, with a 3 chiều Config Editor and consolidated access to all nDisplay-related features & settings in a single UAsmix. There"s also support for OpenColorIO for accurate color calibration, & Beta support for multi-GPU rendering, together with easier multi-camera configuration.

Production-ready Pixel Streaming

Pixel Streaming is now production-ready, with a host of unique improvements và an upgraded version of WebRTC. In addition, we’ve sầu added tư vấn for Linux. This powerful giải pháp công nghệ enables Unreal Engine & applications built on it to run on a high-powered cloud virtual machine và to deliver the full-quality experience to kết thúc users anywhere on a normal web browser on any device.

Previous release notes

Production-ready Hair & Fur

The strand-based Hair và Fur system is now production-ready, giving you the ability to lớn simulate & render high-chất lượng hair, fur, & feathers to create believable humans và animals. The system features built-in LOD generation và is compatible with effects such as DOF & Fog. Cards & meshes can be generated in engine for lower-kết thúc hardware (Experimental).

Sky, cloud, & environment lighting (Beta)

tác giả and render realistic or stylized skies, clouds, và other atmospheric effects with full artistic freedom, with a new Volumetric Cloud component that can interact with Sky Atmosphere, Sky Light, & up khổng lồ two directional lights. Components can be lit và shadowed dynamically, in line with time-of-day updates in real time.

Water system (Experimental)

Create believable bodies of water within your landscapes with a new Water system that gives you the ability lớn define oceans, lakes, rivers, và islands using splines. Built-in fluid simulation enables characters & objects lớn realistically interact with the water; the fluid also responds lớn Terrain, such as reflecting ripples off the shore, and reacting to lớn river flow maps.

Movie Render Queue enhancements (Beta)

You can now output render passes, including matte IDs, camera motion vectors, Z-depth, ambient occlusion, reflections, and more, from the Movie Render Queue. In addition, there’s now tư vấn for OpenColorIO (OCIO), & for exporting multi-channel EXRs, Apple ProRes và Avid DNxHR codecs, and Final Cut Pro XML EDLs, as well as the ability khổng lồ integrate render farms.

Animation in Sequencer (Beta)

It’s now possible to lớn create animations by blending animation clips (such as motion-captured data) directly in Sequencer, with the ability khổng lồ pReviews skeleton animations & match joint placement for a smooth transition between clips.
