Hi, When we apply facial animation to the MetaHuman, the head detaches from the body. Here is a picture where you can see the issue:

Hi <@1074631217783250984>, are you using Convai Face Animation blueprint and if so did you do any changes over it?

have you made any changes to the bp? or to the constructor script of the MetaHuman?

Do you have any other metahuman without this issue that we can compare with?

This issue occurs when we apply facial animation in the NPC blueprint. For example, playing an animation like anger using Convai Actions causes the problem. However, body animations work fine.

I see, but how are you applying the facial animation, basically I am looking for any steps to follow in order to replicate the issue

We are just using the Play Montage node and providing our animation in the montage to play.

ahh I see now what you’re trying to do, to do that you would need to apply the following changes over the Convai Face Animation Blueprint

No, the same problem persists. The montage was working fine, and I had already added the Default Slot node to play the montage, but the head still detaches from the body.

You need to add the layered blend node as well with the same config as in above image

Ensure you have the very same setup as above, and ensure you removed the original default slot you have added, basically start with a fresh Convai face animation bp
