Now Reality Engine supports Panasonic AW-UE150 tracking data and provides its lens calibration file.


Reality Engine can now parse "-rgraph" cmdline parameter to load an initial .rgraph file

This can now open the cooked .uproject file with RealityEngine.exe and load its .rgraph file via the cmdline parameter without Reality Control application. 

Reality Engine Video I/O

AJA Video I/O Re-Write

New   node is introduced with support for UHD TSI, some 3G Level B, hardware Fill and Key and Embedded audio.

Re-write of GPUDirect™ API implementation which supports DX12

GPUDirect™ is important for video output performance especially for outputting UHD or using DXR API (DX12 is the pre-requisite for DXR) to render scenes with real-time ray tracing.

Hardware Fill and Key support

Now it is possible to get hardware synchronized Fill and Key signals from AJA card’s physical ports with the introduction of .

Previous Fill and Key was only limited to software synchronized ports by feeding fill and key images to AJA card's output ports.

AJA Video Output modes selection simplified

AJA output node properties are now exposed based on output , and  selections.

This will ensure proper settings are selected for that device and only technically possible hardware combination.

AJA I/O Device selection simplified

Now, AJA card model will be displayed in drop down selection instead of just “Device”.

AJA Video I/O old nodes are now deprecated

With the introduction of improved and enhanced new AJA video I/O nodes in 2.8, old AJA video I/O nodes are now deprecated.

.rgraph containing older AJA nodes will still be loaded with version 2.8, but they are not available for new addition to the .rgraph. Please update your existing .rgraph with new AJA nodes

AJA Kona5 Video I/O board support (Experimental)

AJA Kona 5 board is still supported only as experimental.

Reality Engine Nodes

Level Sequencer Node added (Experimental)


Level Sequencer Node is added as an experimental feature which can now play and control the sequencer within the Reality Control application.

More information Level Sequencer

Tracked Billboard support for Talent Tracking

 node supports third party talent tracking systems, using this data, talent can walk in front and go behind of a virtual 3D object automatically without any human operation.

In addition to correct object ordering, correct depth position results in correct talent reflection and virtual shadow casting.

Keyer FOV Softness Node added in Reality Keyer

 node is intended to feed Core Matte Softness parameter of the Reality Keyer. The softness radius of the Core Matte is relatively in accordance to the Camera Lens FOV.

More information on Keyer FOV Softness.

Spawned Actors’ synchronization

If actors are Spawned in the Unreal world, they get spawned in the Reality .rgraph and when they are destroyed in Unreal world, they get destroyed in Reality .rgraph as well.

This synchronization of spawned actors are possible both in cooked (Shipping) and Standalone (Editor) mode.

Mo-Sys Jibkit Tracking support

 node now supports the Jib arm length parameter and the Jib tracking parameters.

Mo-Sys UDP Node (Experimental)

New transmission protocol of sending tracking data over UDP with an Ethernet connection.

This new UDP node has optional lens information data being sent by Star Tracker.

Previously Mo-Sys F4 protocol was only available over serial connection.

Introducing Audio Mixer Node

 node allows mixing levels of various audio channels. Multiple audio channels either coming from virtual set audio, embedded audio from video I/O card or UEmedia player audio can be connected to the audio mixer and each channels level can be controlled independently.

More information on Audio Mixer node.

Audio Delay Node

 node sets delay for each audio channel ranging from 0 to 5000 milliseconds. Audio delay can be used to restore sync and compensation for timing shift in audio and video output.

More information on Audio Delay node.

Virtual Set Audio Node is now no more experimental

To make the audio in the virtual set actually sound like it should sound in real world, node provides tools to mold the sounds in the virtual set to give them the desired feel.

More information on setting up Virtual Set Audio node.

Reality Control

Behavior changes of Node selection

More information on Node selection changes.

Node Deletion with Keyboard

Now Delete selected node(s), single or multiple nodes on keyboard  button.

Cosmetic enhancements and GUI icon changes

Control applications’ graphic user interface icons are re-designed for easy access and well categorized views on each tab for clear understanding.

Launcher Tab new icons

Studio Tab new icons

Cook Tab new icons


Collapse and Expanding views

The Reality Engine monitor view sections are organized with bolder headings for better understanding and has option to collapse and expand these view sections.

Empty Reality Engine Cache Folder directly from Control application

New updates in Reality Engine 2.8 make user operation faster and simpler by adding some simple but useful features like “Emptying Reality Cache Folder”. Now you can empty the contents of Reality cache folder from Control application itself and the same action is also available in Reality Engine GUI just click on the  button and that’s it!

Cook Server

Support for long paths for cooking process (Experimental)

Reality Engine 2.8 adds support for long file paths for cooking process. Now you can have long paths and not restrict to 260 characters.

Improved Cooking Speed

Cooking process time is now faster by 20-30 seconds.

Now cooking process is even faster than ever with intelligent way of handling the cook process. When cooking a project, engine content is excluded and only the shader and other components of content will be compiled. And, while cooking same project multiple times, it will take "engine content" from the Reality Engine installed folder thus avoid re-cooking  folder for each cook.

More information on Cooking a Project.

Cook Server is an optional component of the Reality Editor installer

More information on Cook Server installation guide.

Media Playback

Introduction Of Hardware Accelerated Video Decoding

Reality Engine can now use your GPU to speed up the processing of H.264 video streams. This will decrease the CPU load by up to 80% by making all the media process on GPU when playing back video streams, which may result in smoother video and may allow you to use higher resolution movie files and more simultaneous input feeds.
