Critical Render Simulation Error with CC5 Characters in UE5?

Hello,
I’ve encountered an issue with CC5 characters in UE5. I’m using the v2.0 version of the plugin. When simulation/rendering is disabled, all facial movements (eye-closing, mouth-opening) work perfectly fine. However, once simulation is enabled, a double character overlay issue occurs. It seems that the feature to hide the head and body parts in the new v2.0 blueprint has stopped working, which has been quite frustrating.
Have you also come across this issue? Could you please help me resolve it? Thank you.

Hi Steven.

This is definitely a bug.
After conducting various tests, I've proven that this phenomenon occurs in the new Autosetup 2.0 but not in the previous version, Autosetup 1.4. Could you please review the video?
This time, I prepared two Aeron models. One was imported using Autosetup 2.0, while the other was imported using Autosetup 1.4 in a separate project file and then migrated over. The result is that when playing the sequencer with simulate pressed, only the one imported with Autosetup 2.0 exhibits the faces overlapping.
Additionally, the Autosetup 2.0 one always displays a large number of error messages after simulate. This also does not occur with characters from Autosetup 1.4.

One more point: I don't know the cause of this phenomenon, but please check the second video. This Aaron animation was imported directly from a CC5 template project with no modifications. For some reason, adding body animation makes the face overlap disappear. However, applying body animation unrelated to the template project causes the problem to reappear.
However, if you imported using autosetup1.4, the face duplication problem doesn't occur at all, regardless of which body animation you apply, or even if you apply only the face animation itself.

If you insist this isn't a bug, could you please perform the same steps I did? I perfectly replicated the tutorial method you provided and also tried baking the animation to the control rig. The problem persisted.

I've also tested with various other face animations.

Please address this issue seriously. I've been completely unable to render and have been in real trouble these past few days.

Hi.

I have the exact same problem.
Using the Blueprint_CC_ContrlRig and hit simulate, a double character overlay issue occurs.

It happens when I render it too.

I know this same phenomenon occurs when replacing the Blueprint for Metahuman with CC5, but it also happens when you want to use CC5 characters directly.
 
Please watch the video.

Hi 古月羊毛卷,
I seemed to have problems reproducing your issue.
Can you provide your UE project and FBX exported form CC?
Thanks a lot.
