Error: Could not apply LiveLinkPreset in UE 5.4 game mode

[gammatrix5]

Hello

UE5.3 works well with Audio2Face 2023.2.0 in game mode (certainly editor mode also works fine)

Then I tried the same plugin in UE 5.4.1, it failed with the following error in game mode(editor mode works) .

The following error can be found in log when game starts

LogLiveLink: Warning: Create Source Failure: The settings are not defined.
LogLiveLink: Warning: Create Subject Failure: The source doesn't exist.
LogLiveLink: Error: Could not apply 'LiveLinkPreset /Game/A2FLiveLinkPreset.A2FLiveLinkPreset'

I created the live link as below.

It works in editor mode and I can see lip animation.

Then store it as a preset.

Edit the blueprint to apply this preset when application starts.

The same configuration works fine in UE 5.3.2 but failed with above error in UE 5.4.1

When the game is being built, I see the following warning messages. Unsure if this is related.

Errors from Audio2Face log, it cannot connect to port 12030. I checked and actually this port is not listened.

Can you please share from where you copied omniverse plugin from and its version info? Thanks.

I copied it from audio2face-2023.2\ue-plugins in my Audio2Face installation folder, for UE 5.3

Hi @dmohsin

here is my installation path

I copied ACE folder from F:\omniverse\pkg\audio2face-2023.2.0\ue-plugins\audio2face-ue-plugins\ACEUnrealPlugin-5.3 into Plugins directory of my UE project.

It works fine in UE 5.3.2 but fails in game model of UE 5.4.1

LogLiveLink: Warning: Create Source Failure: The settings are not defined.
LogLiveLink: Warning: Create Subject Failure: The source doesn't exist.
LogLiveLink: Error: Could not apply 'LiveLinkPreset /Game/A2FLiveLinkPreset.A2FLiveLinkPreset'

As there is no official release of the plugin released for UE5.4, you will not be able to package the plugin with 5.4 until there is a release for 5.4. Alternatively you can build the old plugin with UE5.4.
