UE 5.3 support

[p.f.zeratul]

When will we get UE 5.3 support?

I tried to build the plugin myself, I succeeded in building the Plugins folder with BuildUnrealPlugin.Bat but failed when building Source folder with BuildMayaUnrealLiveLinkPlugin.Bat, what am I doing wrong?

So, I see that UnrealHeaderTool is removed in UE 5.3, so there may not be an easy fix.🙁

I'd also love to know as well if there's an ETA on the updated plugin for 5.3.

Hello, 

Unfortunately we cannot give an ETA for when a plugin for UE 5.3 will be released, but it is in our plans to release one.

Best Regards,

Carlos

Hi, 
You can try https://github.com/Autodesk/LiveLink/pull/31 , it should work for UE 5.3.2.

Sincerely,

Powen

Just bumping this thread -- see if there's any updates on a UE 5.3 LiveLink plugin?

As Powen mentions above, there's a fix for 5.3.2 on GitHub, but it would be great to know when an updated version would be available for download. 

Thanks!

Hi everyone, thanks for your patience, the UE 5.3 Livelink plugin is now available and an option to toggle real-time synchronization of data has been added with performance improvements using linked assets.

We're now working on updating Livelink to the newly release UE 5.4 and looking into additional real-time support between Maya and UE, stay tune for updates!

Nothing is wrong with your command syntax. The failure is caused by UnrealHeaderTool not being available in your engine build and by attempting to compile a Maya Live Link plugin against an Unreal Engine version it was not designed for. The safest solution is to use the officially released Live Link plugin version that matches your Unreal Engine version exactly.
