Operation

OBJ production

When making OBJ accessories in other 3D programs (Maya, 3ds Max, etc.), please follow the requirements below.

• Set the work environment of the 3D program. (Axis: Y-Up, Unit: Millimeter)
  
  
• Create a hair/shoes/glasses/earring OBJ according to the avatar file:
  
  

  Avatar	Prepare an avatar suitable for the hair/shoes to be registered. Marvelous Designer's default avatar or user avatar can be used.
  Mesh	For the sharp angular expression, add an edge to the mesh to be reliably simulated in the Marvelous Designer.
  Dummy Mesh	For complex areas (shoelaces, heels, etc.) where the faces come into contact, wrap in a transparent and flat dummy mesh. Make the spacing between dummy meshes smaller and more consistent than shoe meshes.
  Mesh Name	Hair	hair
  	Shoes	(shoes_r, shoes_l)
  	Glasses	(glasses_r, glasses_l)
  	Earring	(earring_r, earring_l)
  Materials	Apply separately, various materials (leather, metal, plastic, etc.) Even if the heel is the same material, it must be applied separately, and the order must be at the bottom.

• Set the transform properties. (Translate/ Rotation: All axes 0, Scale: All axes 1)
  
  
  
• Export to FBX file.
  
  ※Note:
  • .obj files don't contain unit information internally
  • With autoscale enabled, software estimates units assuming human-sized objects
  • When using .obj files, remember and use the same unit setting during export and import
  • .fbx format stores unit information internally, making autoscale import work correctly

Registering Accessories

1. Open the avatar file for the hair/shoes/glasses/earrings to be registered to. 
   ※ Note: It is recommended to review the placement of the (FBX) file (hair/shoes/glasses/earrings) that is intended to be registered and check that the position with the avatar is correct before you register it as an accessory.
   
   
2. Select the tool/menu indicated in Location.
   → The Register Accessory window appears.
   
   
3. After setting the following options, click the Save button.

   ※ Note: Make sure the mesh layer noted below has the correct nomenclature in Blender. The other names do not matter. Otherwise, you may encounter an error message that the name is wrong.
