Hi @Juanxd7777249 ,
Streaming And Hlo Ds | Unreal Editor For Fortnite Documentation | Epic Developer Community (epicgames.com)
When creating UEFN project using the Migrate function from UE5 the validation failed you must import as FBX by Export from UE5 project

Then you can set all the setting on import
