The overall process is identical to the Fur workflow of LiveSync 1, which can be found in the following documentation: [Experimental] Expressing Fur in Unreal Engine via LiveSync.
From CLO 2025.0 and Marvelous Designer 2025.0, you can choose a new Fabric type, Fur_Strand. You can use the new Fabric type to check for intermediate results directly in the 3D Window using Default Render Mode and Quality Render Mode in CLO and Marvelous Designer, before bringing the garment to Unreal Engine via LiveSync.
