Unreal Engine 5.3 Released

[OverRated_AU]

World partition is bugged on 5.3 for clients that are running on dedicated servers, collision for landscape cells don’t always get loaded anyone else having this issue? 5.2 didn’t have this issue.

[PaPaParker9]

On m1 Macs, VR Template crashes at start up. In Config/DefaultEngine.ini, turn off r.ForwardShading

r.ForwardShading=False

Then UE 5.3.1 VR Template doesn’t crash at start up.

[DigitalGreenTea]

I’ve upgraded my project from 5.1.1 to 5.3.1. When using Android Vulkan Preview Shading, the editor crashes with the following error message:
“failed to find shader type FPopulateCompositeDepthPS in Platform PCD3D_ES31”

I don’t know how to fix this issue as I can’t find anybody experiencing something similar on Google or here. The game I’m making is intended to be a mobile game. I’m on Windows 11. Any help would be very appreciated!

[Pawpatting (Pawz)]

Anyone else here experiencing this issue? Ever since UE5.3 the editor flickers golden in this way. Its made even worse when I hover over the outliner with my mouse.

[Gimli_Gloin]

5.3 is much more performant than previous versions, please add the functionality to take an IK Rig into a Control Rig, or generate Control Rigs from IK Rigs.

@Gimli_Gloin

IK Rig into a Control Rig

Control Rig Full-Body IK in Unreal Engine | Unreal Engine 5.3 Documentation

Control Rig in Unreal Engine | Unreal Engine 5.0 Documentation

Unreal Engine IK Rig | Unreal Engine 5.0 Documentation

Search IK Rig - Unreal Engine

[Gimli_Gloin]

docs don’t show conversion of an IK Rig to a Control Rig or using an IK Rig in a Control Rig, using solvers an IK Rig asset uses inside a control rig is not what I’m looking for, the request is to be able to lets say drag and drop an IK Rig into control rig and all the solvers and goals would be generated and from there further customization can be made

[EddieChristian]

We can’t even open a folder with Chaos objects in it because the Editor crashes in 5.3.1 . Always get a Loss of data caused by narrowing conversion Error. @Amanda.Schade

[Miguel1900]

@Amanda.Schade , please, remember the innumerable bugs that still exist in virtual reality (since UE5).

Thank you

hi everbody,

After switching to 5.3.1, I am experiencing huge drops in my fps rates on my map, I dropped from almost 60 fps to 20, plus lumen and virtual shadow are turned off.

[Sergey_Skyline]

Good afternoon.
Your client accidentally does not show a warning
(LogNetPackageMap: Warning: Using None instead of replicated reference to LandscapeHeightfieldCollisionComponent //Maps//Generated/56EBXNPE.map_name:PersistentLevel.LandscapeStreamingProxy_94G6F8OD_126_1_2_0.LandscapeHeightfieldCollisionComponent_35 because the level it’s in has not been made visible )

If so, then I am with you on the same problem.
The problem is not fixed in 5.3.2
In 5.4.0 (build date October 30), the problem was not found, BUT this version cannot be used in production.

I went through almost all the fix options until I ran out of imagination.
I’ll probably write a post about this by the end of the week.
It’s unlikely that they will have time to solve the problem by the release of 5.3.2, but I hope they will help me with a git commit that fixes this problem.

@Amanda.Schade

Get your hands on Unreal Engine 5.3 today. With this release, developers will gain access to expanded functionality in UE5’s core rendering, development iteration, and virtual production workflows. Plus, explore a slew of new experimental rendering, animation, and simulation features!

Download Unreal Engine 5.3 from the Epic Games launcher, GitHub , or for Linux !

Refinements to core UE5 rendering features

Nanite has faster performance for masked materials, including foliage, and can represent a greater range of surfaces due to the new Explicit Tangents option.

Lumen with Hardware Ray Tracing has expanded capabilities that include multiple reflection bounces, and delivers faster performance on consoles.

Other areas with notable advancements include Virtual Shadow Maps (VSM)—which is now Production-Ready—Temporal Super Resolution (TSR), Hair Grooms, Path Tracing, and Substrate.

Multi-Process Cook

Enabling Multi-Process Cook launches subprocesses that perform parts of the cooking work alongside the main process, significantly reducing the time it takes to get a cooked output from a build farm server or on a local workstation.

Cine Cam Rig Rail

Emulate the workflow and results of traditional camera movement along tracks or on dollies, thanks to a new Cine Cam Rig Rail Actor, which provides more refined controls, including the ability to choreograph settings like camera rotation, focal length, focus distance, and so on, at different control points along the path. It supports both in-editor and VCam workflows.

VCam Enhancements

Enhancements to the VCam include the ability to review takes directly on the iPad for faster iteration; to simultaneously stream different VCam output for different team members—for example, with camera controls for the camera operator, without for the director—facilitating collaborative VCam shoots; and to record at a slower frame rate and playback at normal speed for easier capture of fast-moving action.

Experimental features

Please try them out and send us your feedback , but keep in mind these features are still under heavy development and we don’t recommend using them in your final projects just yet.

Sparse Volume Textures (SVT) and Path Tracing of Heterogeneous Volumes introduce a number of new capabilities for volumetric effects such as smoke and fire. SVT store baked simulation data representing volumetric media, and can be simulated in Niagara or imported from OpenVDB (.vdb) files created in other 3D applications. More complete support for rendering volumes is now available in the Path Tracer, offering the potential for high-quality volumetric rendering—including global illumination, shadows, and scattering—for cinematics, films, episodic television, and other forms of linear content creation.

Orthographic rendering is useful for visualizing architecture and manufacturing projects, as well as offering orthographic projections as a stylistic camera choice for games. Most modern features of UE5 are expected to now work, including Lumen, Nanite, and Shadows. Orthographic rendering is also available in the Unreal Editor.

A new Skeletal Editor provides animators with a variety of tools for working with Skeletal Meshes, including the ability to paint skin weights—in editor.

We’ve introduced a new Panel Cloth Editor and new skin weight transfer algorithms, and added XPBD (extended position-based dynamics) constraints as a basis for our future cloth generation in engine. This provides a non-destructive cloth simulation workflow in which you can trade off speed for precision, and can result in better-looking simulations. Cloth can also now be simulated and cached in engine using the new Panel Cloth Editor in conjunction with the ML Deformer Editor.

Known Issues

For a complete listing of known issues affecting Unreal Engine 5.3, please see the Unreal Engine Public Issue Tracker .

• Some users are encountering an error message that the “Plugin ‘Fab’ failed to load because module ‘Fab’ could not be found.”Workaround this issue by removing the UE_5.3/Engine/Plugins/Fab folder.
• In Unreal Engine 5.3, the default scheme in Xcode is incorrectly set to UnrealGame (or your project’s Game scheme). Select UnrealEditor (or your project’s Editor) scheme in the Xcode scheme dropdown.

These features introduce new capabilities for volumetric effects such as smoke and fire. SVT allows you to store baked simulation data representing volumetric media, which can be simulated in Niagara or imported from OpenVDB (.vdb) files created in other 3D applications. The Path Tracer provides more complete support for rendering volumes, offering the potential for high-quality volumetric rendering, including global illumination, shadows, and scattering.

The anim curve of version 5.3 is completely broken, and so far the anim curve is still not working properly.The value of anim curve in the animation blueprint is always 0, no matter whether anim curve is set or not in the animation sequence.

and I found the function “get all curve names” return a empty array.

Finally I solved this “bug”. It’s because the function of the “curve source” animation blueprint node has been modified or fixed by EPIC, which in turn caused the “bug” in my project.

Nice to see 5.3.2 hotfixes out I am stil unfortunately disappointed by the insane flickering seen on some legacy masked foliage assets with Lumen though.

I know the recommendation is to bug report, but this is something I’ve reported more than once since 5.1 including video recordings of exact repro steps on a completely blank project…still never confirmed nor addressed.

Are masked trees (e.g. pine trees) just abandoned then?
