Unreal Engine 4.27 is Here!

The Unreal Engine 4.27 update, published by Epic Games two days ago, includes a plethora of intriguing new features for game developers as well as filmmakers and architects. Enhancements to the virtual production toolset for in-camera visual effects include:

  • Significant alterations have been made.
  • GPU Lightmass enhancements allow for quicker light baking.
  • The Oodle Compression Suite has been included.
  • Unreal Engine users may utilize the Bink Video codecs for free.
  • Pixel Streaming is ready for use in production.
  • OpenXR support that is ready for production.
  • Added features to Datasmith that were previously unavailable.

VFX operations that are more efficient when done in camera 

When it comes to using the Unreal Engine’s in-camera visual effects (ICVFX) toolbox, version 4.27 has made it faster and easier.

The new 3D Config Editor in 4.27 makes it much easier for users to configure their display settings for generating models with quick seed for LED volumes and other multi-display rendering applications. When creating a 3D character model, you’ll now have easy access to all of your previously specified materials. A single nDisplay Root Actor now contains all display-related settings and functionality. Now that it supports several GPUs, nDisplay will be able to scale better. Users can use numerous cameras, each with its own tracked frustum, to achieve the highest possible image quality on large images with support for more than one GPU. It’s now possible to use Unreal Engine content with nDisplay thanks to OpenColorIO support.

As well as supporting new features including Multi-User Editing, a redesigned user interface, and extensible core architecture, version 4.27 enhances the Engine’s virtual camera. Customers may use the new iOS app Live Link Vcam to operate a Cine Camera in-engine with an iPad. Now that improvements have been made, moving photographs taken with a physical camera with a moving backdrop will have improved motion blur.

Using the new Level Snapshots feature, you may quickly revert to a previous setup for pickup shots or creative adjustments by preserving the current state of a scene and then restoring any or all of its elements as necessary.

Faster light baking

In Unreal Engine 4.27, GPU Lightmass has gotten a boost from better feature support and increased stability. DirectX 12 ray tracing and Microsoft’s DXR framework are used to render pre-computed lightmaps on the GPU rather than the CPU.

When rendering complex lighting effects like global illumination, soft shadows, and other expensive real-time rendering effects, GPU Lightmass saves time by generating lighting data more quickly. Because users can see the impacts as they go, making modifications and restarting without waiting for the final bake is considerably easier. In a matter of minutes, you may alter the color of any 3D character model. Get free 3D Models at FrogModel

Final-pixel imagery made easy.

In Unreal Engine, it’s a physically accurate progressive rendering approach for 3D character models that makes use of DXR acceleration and doesn’t call for any additional setup. A number of Path Tracer enhancements in 4.27 have made it feasible to provide final-pixel images on par with offline renderings. Improvements include more accurate global illumination and refraction, full reflection and raytracing materials, and super-scaled anti-aliasing for 3D character models and all other sorts of models, amongst other things..

In order to render several cameras at the same time, you no longer need to use time-consuming Sequencer setups. It’s now much easier to create large stills while going through creative revisions or variants because of this.
