Hello together, I was made aware of this forum by a friend.
The main objective was to test the realtime physics with constraints (Zipper slider/Earrings) in UE 5. For close-up shots of faces, I would like to distract the viewer a little from the facial expressions.
I threw together a few clips that I used with iClone Live Link/CC4 Character and MrQ Lumen Render.
Greetings @Ray_Trace !
Welcome back! Those earrings are fire! 
The way the light reflected off the earring’s facets was mesmerizing! The Metahuman looked like an homage to 90s Halle Berry, strutting proudly down the street showing off her ultra cool futurist clothing and accessories. Thank you so much for sharing!
In your objective in testing the real time physics, what have you learned?
Awesome work ! Earrings , Emissive & Cloth are marvelous ! 
Hello Get_DOVAH_it, thank you for your words and the eye for details!
It makes me happy that you like it. BTW, it is a pure CC4 Character.
Regarding realtime physics:
It’s running fine.
In the very first video on my YT Channel (iClone 7 Body Live Link Unreal Engine 4.27 with Metahuman Head and Physics in Realtime. WIP - YouTube), the clinker bricks hang directly on the suspension and are held in place well by the hardbody simulation. Until recently I was still on UE 4.27 because it didn’t work that way in UE 5. Lost a lot of hair. But got it under control now.
In UE 5 you have to rethink. The small parts explode in all directions. Hence, the idea of ​​using a floating suspension to trick. Just don’t lose your nerve to get the constraints under control. Especially with small dimensions.
Hey StyleMarshal,
thank you very much for the motivation and for your support!
