     If you want to adjust texture scale, activate U/V Tiling and control it on the Global Scalar Parameter Va tab. You can change the texture color with Color Tint on the Global Vector Parameter Va.

     
     
   • When it is succussed, there will bezls folder in the Content Browser
     
   • Inside the ZLS folder, there will be a folder which has the same name as zls file (*.zls)
   • Drag and drop the blueprint class file into the viewport
     
     

     ※Note: If some patterns are invisible, turn on he Show Thickness option on the pattern properties or turn on the Two Sided option on the `Material Editor`

     
     

2. Set the transform(location) of the garment to match that of the avatar.

   You can change the deform values if you need a more sophisticated arrangement.
   

3. On the left Placer Actors, search Zelus Simulation Manager and drag-drop it into a viewport. If applied successfully, the zls actor is created in the outliner.
   
4. Click Zelus Simulation Management on the outliner and set the simulation properties.
