Critical Render Simulation Error with CC5 Characters in UE5?

Character Creator Bugs & Issues
1

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.
