Chaos cloth won't validate

Hi,

I’m following the official Epic documentation to create cloth for a custom character, but the UEFN Validator keeps failing.

My Workflow:

- Created Chaos Cloth Data in UE 5.4 (standard Max Distance painting).

- Migrated the Skeletal Mesh and Cloth Asset to UEFN.

- Validation fails with: “Skeletal mesh contains invalid data”.

Is there a specific list of forbidden Chaos Cloth parameters for UEFN/Fortnite?

Thanks!
