Modular Metahuman character with Chaos Cloth physics and body physics - Skeletal mesh merge?

Hi guys,

I’m trying to set up a modular Metahuman character.
The idea is to switch physics simulated clothing at runtime through blueprints.
I am using the new Chaos Cloth workflow.

As far as I understand from this documentation (Working with Modular Characters in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community), I have to use skeletal mesh merge to have physics on multiple skeletal meshes.

Now the problem is that I have Chaos Cloth assets in my character BP, and not skeletal meshes like with the legacy cloth physics in skeletal meshes.

Moving ChaosCloth_Legs below Legs for example (not sure if that would make a difference) crashes Unreal every time.

How can I have physics simulation on body and clothing at the same time this way?

Thanks for any tips!

Any ideas anyone?
