Unreal Engine 4.26 released!

With the release of Unreal Engine 4.26, you can create environments, characters, and creatures of unparalleled realism and design your entire production pipeline around Unreal Engine.

The production-ready Hair, Fur, and Feathers system enables you to design the most believable humans and animals. You can use the Volumetric Cloud component along with the Sky Atmosphere and Sky Light to author and render realistic or stylized skies, clouds, and other atmospheric effects with full artistic freedom. The new Water System makes it possible to create believable bodies of water within your landscape terrains that react with your characters, vehicles, and weapons. With an improved and expanded feature set, Chaos physics now lets you simulate Vehicles, Cloth, and Ragdolls in addition to Rigid Bodies so every aspect of the environment comes to life.

Sequencer works in conjunction with Control Rig and the new full-body IK solution to create new animations inside of Sequencer, reducing the need to use external tools. Movie Render Queue (formerly known as High Quality Media Export) has been enhanced to support render passes enabling further enhancements to be made to the final image in a downstream compositing application. nDisplay multi-display rendering is easier to set up and configure in addition to enabling more pixels to be rendered at a higher frame rate, thus increasing performance and supporting larger LED volumes with existing hardware. The Collaborative Viewer Template has been significantly improved to enhance the collaborative design review experience, and enable more users to join a session. The Remote Control API has been improved to seamlessly connect properties and functionality in Unreal Editor to UI widgets giving users the ability to quickly change properties from an external device, such as an artist on stage changing the sky rotation or the sun position from an iPad.

I see you write “Chaos physics now lets you simulate Vehicles, Cloth, and Ragdolls in addition to Rigid Bodies” does this mean we can utilize chaos without compiling from source? Considering the delays and rollback to PhysX, can I choose to run vehicles in chaos with the launcher version? :slight_smile:

Is the new “Remote control web interface” plugin missing from this release? I have just updated, following the tutorial here ->

Remote Control Presets and Web Application | Unreal Engine Documentation

and the plugin is not visible to me.

I have the same - only seeing OSC, Remote Control API and Slate remote on a search

Could we get a date on the Remote Control 2 app update as well please? :slight_smile:

"Chaos Physics is the lightweight physics simulation solution used in Fortnite . With this beta release, we are making it available for developers learning to work with this feature. PhysX is on by default with Unreal Engine 4.26 (available in the Epic Launcher) and will be deprecated in a future release when Chaos Physics is enabled by default,"

Hi!
Could anybody help me?
I can’t find Take Recorder Functions in Blueprint Library in 4.26.
Unreal 4.25 has it, and I found C++ file in 4.26 where Take Recorder Functions existing. But in blueprints I don’t have allow to these functions
Take Recorder plugin is enabled

Richtext is broken for me in 4.26.

Any text inside a richtext tag takes up negative amount of space, instead of appropriate space.

Anyone knows how to fix it or is it an unfixable bug until the next hotfix?

Exactly, that freaked me out when I saw that.

The take recorder blueprint functions are only available in an editor utility blueprint, since they are editor only functions.

Not exactly sure what’s going on, but it seems like either this a 4.26 bug, or behaviour has changed. This setting below regarding Auto Possess AI now blocks the player controller from receiving the OnPossess event. 4.25.(1) did not have this issue, and I had a friend test in his 4.26 as well, same behaviour.

To clarify, I can possess something, just the OnPossess event does not trigger.

constant crashes…when moving around the interface, resizing windows, trying to render using movie render queue etc…

4.26 preview 7 error [guaranteed to occur after movie render queue slowly renders one still frame and as log message window appears ‘bam’ d3d error!]

then just updated to full release 4.26 [slightly less crashes [but still more than enough] on moving around/interacting with interface but still cannot use Movie Rendcer Queue to render a still without crashing]. The error has now evolved but still the good ole d3d12RHI error involved.

project is fine within 4.25.3…only copied and inplace converted it to 4.26 p7 project for volumetric clouds. aside from this there is noi difference between the two projects.
