MetaHuman A2F plugin (ACE) error loading behavior UE 5.3

MetalGandix · July 9, 2024, 9:25am

Hi to everyone,

i’m tryng to lipsync my metahuman with ACE plugin:
https://docs.nvidia.com/ace/latest/workflows/kairos/kairos-unreal-plugin.html

i have the “SoundWave” file that is generated by ElevenLabs, and i want to lipsync that wav with my metahuman.

I implemented the ACE plugin but i receive the error:
“LogACERuntime: Error: Couldn’t read USoundWave ImportedSoundWave /Engine/Transient.ImportedSoundWave_0, try setting LoadingBehavior to ForceInline” as you can see in the image.

I implemented the plugin like that:

i tryed to change the “loadingBehaviour” with a custom method on C++ like that:

but at this point i don’t think the problem is the “loadingBehaviour”.

What am i missing?

Thanks!

Hi
I solved the problem this way:

Find the Sound Wave asset you are using
Double-click the Sound Wave asset to open the details.
Under the “Loading” category, change the “Loading Behavior Override” option to “ForceInline.”

Thanks for the answer!

I can’t find “loading” properties inside my “details panel” if i double click on my sound wave:

Am i misunderstanding something?

hi,

Try the sound Wave file in the content drawer. the audio file !

MetalGandix · July 23, 2024, 9:55am

Thanks again for the answer, but i don’t have the audio file, because it is generated by “ElevenLabs”, so i don’t have the “asset” i just have the variable.

Can i create the file based on the variable soundwave?

There is another node you can use which is to animate it from a .wav file.

Which worked for me (also using elevenlabs)

MetalGandix · September 23, 2024, 7:53am

Thanks for your answer.

Sorry i don’t understand, how can you use Eleven labs with “animate character from Wav File” if you don’t have a Wav file?
Because Eleven Labs doesn’t give you a “Wav file”, am i wrong? Can you share your blueprint please?

Thanks again for your time!

You should get pcm data from eleven labs. Then convert it to a wav file.

Hi, I have the same trouble but with Convai… i can catch internal sound within engine into Sound Wave, but the same error appear when trying to animate character with ACE((

I even can’t find the node “Set Sound Wave Loading Behavior”. It’s a part of what? don’t know if I need it, if it’s not working too…
