Unreal Engine 5.1 is Now Available..!
Telugu super news,November 16th,India, 2022: Unreal Engine 5.1 is available today, building upon the groundbreaking feature set introduced inUE5 to enable even easier and faster 3D content creation. A range of stress-tested newfeatures and improvements in 5.1 make Unreal even more robust, efficient, and versatile forcreators across all industries.
Games
As over half of all announced next-gen games are being created with Unreal Engine, developers
can now take advantage of updates to the Lumen dynamic global illumination and reflections
system, the Nanite virtualized micropolygon geometry system, and Virtual Shadow Maps
(VSM) that lay the groundwork for games and experiences running at 60 frames per second
(fps) on next-gen consoles and capable PCs. These improvements will enable fast-paced
competition and detailed simulations without latency.
Additionally, Nanite has also added a Programmable Rasterizer to allow for material-driven
animations and deformations via World Position Offset, as well as opacity masks. This
exciting development paves the way for artists to use Nanite to program specific objects’
behavior, for example Nanite-based foliage with leaves blowing in the wind.
UE 5.1 also adds several features to improve efficiency for developers of games and other
large-scale interactive projects, helping teams be more productive. For instance, Virtual Assets
decouple the metadata from the object data, enabling developers to sync only what they need
from source control systems such as Perforce—resulting in smaller workspaces and faster
syncs for developers who don’t need access to the full object data. The new automated
Pipeline State Object (PSO) caching for DX12 simplifies the process needed to prepare a
game for shipping in DX12. And lastly, on-demand shader compilation compiles only the
shaders needed to render what is seen on screen while working in the Unreal Editor, which can
result in significant time savings and increased interactivity.
For developers building massive open worlds, this release also delivers additional functionality
and improved workflows. World Partition now supports Large World Coordinates, enabling
the creation of massive open worlds without loss of precision. Users can also enjoy accelerated
source control workflows with World Partition, thanks to an improved user experience
around managing, filtering, searching, and viewing files and changelists. It’s also now easier to
find content in the world from within your changelists, and vice versa. In addition, new HLOD
(Hierarchical Level of Detail) support for water rendering and streaming enables users to
create large water bodies in open worlds with better performance and a smaller memory
footprint.
In-Camera Visual Effects
Unreal Engine has now been used on over 425 film and TV productions, and is integrated into
over 300 virtual production stages worldwide. With improvements in Unreal Engine 5.1
specifically tailored to virtual production workflows, technicians and artists now have multiple
benefits, including a dedicated In-Camera VFX Editor, improved Light Card system, improved
Remote Control APIs, expanded color correction tools, initial Lumen support for nDisplay, and
more.
First, LED stage operators can now take advantage of a new dedicated In-Camera VFX
(ICVFX) Editor that supports a range of virtual production workflows. This largely eliminates the
need for stage operators to hunt through the Outliner for specific objects and controls. UE 5.1
also adds UI, UX, and performance improvements for the Remote Control APIs, enabling
users to construct powerful custom browser-based remote controls more quickly and easily.
The ICVFX Editor also hosts an interface to an improved Light Card system that displays as a
preview of the nDisplay wall. As well as making it intuitive and efficient to create, move, and edit
light cards and save templates, the new light cards can retain their shape on the wall,
eliminating distortion.
Also new in the ICVFX Editor are Color Correction Windows (CCWs) that enable color
adjustments to be applied exclusively to anything behind them (similar to Power Windows in
color grading applications), together with the ability to apply color corrections per Actor, which
reduces the need for complex masking.
In Unreal Engine 5.1, the new Media Plate Actor enables OpenEXR support, enabling users to
simply drag and drop footage from the Content Browser. In addition, users can now play back
mipmapped and tiled uncompressed EXRs both in engine and with nDisplay with the
appropriate SSD RAID, and now have the ability to convert EXRs to the correct format for
optimum playback.
Furthermore, Unreal Engine’s virtual camera system has been overhauled with a new
underlying framework that utilizes Epic’s Pixel Streaming technology for improved
responsiveness and reliability, and an updated UI with a modern camera-focused design that
will be more familiar to camera operators. Users also now have the ability to connect hardware
devices, and will be able to customize the UI in the future.
Lumen, Unreal Engine’s fully dynamic global illumination and reflections system, now offers
initial support for nDisplayin 5.1, provided the number of lights is modest (about 5-7 lights
total, depending on graphics card). With Lumen, indirect lighting adapts on the fly with changes
to the sun’s angle, lights, or position bounce cards, for example. Previously, these changes
would have required a baking step that could pause production, interrupting the creative flow.
UE 5.1 also adds improvements to GPU Lightmass, including support for Sky Atmosphere,
stationary Sky Lights, light features such as IES profiles and Rect Light textures, and improved
quality and performance across the board.
Animation
Unreal Engine usage in animation has grown exponentially, from 15 productions between 2015
and 2019 to over 160 productions from 2020 to 2022. For professionals working with animated
content, particularly characters, Unreal Engine 5.1 offers several notable advancements to the
engine’s built-in animation and rigging tools, as well as Sequencer.
Now in Beta, the Machine Learning (ML) Deformer generates high-fidelity approximations of
nonlinear deformers, complex proprietary rigs, or any arbitrary deformation by using a custom
Maya plugin to train a machine learning model, which in turn runs in real time in Unreal Engine.
This enables users to simulate film-quality deformations, such as flexing muscles, bulging veins,
and sliding skin. Other character deformation improvements include enhancements to the
Deformer Graph Editor for easier graph creation and editing.
Also, Control Rig continues to expand toward fully procedural rigging, increasing the impact
and scalability of rigging teams. Updates to the core framework include a new Construction
Event that lets users generate rig hierarchies via a graph, and Custom User Events for creating
and triggering rig events such as “Snap FK to IK.” With these updates, artists can create a
single Control Rig asset that can build itself to fit characters that may have different skeletal
proportions and properties—for example, the same Control Rig can adapt itself to a
three-fingered monster or a five-fingered human without any changes to the rig asset.
Unreal Engine 5.1 also adds support for constraints in Sequencer—the engine’s multi-track
nonlinear animation editor—including Position, Rotation, and Look-at. Users can leverage these
to quickly and easily create and animate relationships between any Control Rig or Actors, for
example, making a camera always follow a character; keeping a character’s hands on a
steering wheel; animating a clown juggling balls; or constraining a cowboy’s hips so that he sits
naturally in the saddle as the horse moves, while his hands hold the reins. Sequencer also sees
additional functionality exposed through Blueprint and Python scripting, and a refactored
UI/UX for increased stability and extensibility, and to improve animation authoring and editing
workflows.
