How to Add Outlines to your model

Note:

  • Outline support is only available from Studio Eleven version 1.3 and above.
  • In the guide, you'll see two different models in the screenshots; ignore them and assume that it's always the same model.

1. Prepare Your Model

Before adding outlines, you need to check that the vertex colors of your model are correct.

Check Vertex color

  1. Enable Viewport shading
  2. Click on any mesh (you'll have to check each of your meshes anyway)
  1. Turn on vertex Paint
    Note: If the mesh appears completely black, that means your vertex paint is correct, and you can move on to the next mesh. (If you have more than one.) If the mesh isn't completely black, it means your vertex paint is incorrect, and you need to fix it. Follow this:
    1. Click on the white square and change the color so that it's completely black
    1. Click on "Paint" and select "Set Vertex Color." Once you've done that, the mesh will turn completely black, which means your mesh is fixed! You can move on to the next mesh (if you have more than one).

Once all the vertex colors for each mesh are black, you can move on to duplicating the faces

Duplicate Selected

  1. Select the mesh you want to outline.
  2. In the Studio Eleven panel, click Duplicate Selected.
    • This duplicates all faces and calculates normals correctly.
    • A notification will appear when the operation is finished.
  3. Important: If the mesh already has duplicated faces, the operation will be canceled to avoid multiple duplications.

Check for Duplicated Faces

You can verify if your mesh has duplicated faces in two ways:

  • Delete a face; if another face appears, your mesh has duplicates. Undo the deletion afterward.
  • Switch to Vertex Paint in viewport shading. If the mesh appears red, it has duplicate faces.

2. Configure Outline during Xpck Exporter

  1. Go to the Export Menu → Outline.
  2. Click Add New Outline.

Note: Even if the faces have been duplicated, if the Outline parameters are not set during the XPCK export, no outline will be visible in game.

Outline Parameters

  • Name: Can be anything; it’s just for identification.
  • Thickness: Controls how many times the mesh is multiplied to create the outline. Recommended: leave default values.
  • Visibility:
    • Lower values → more visible outline (0 = black outlines)
    • Higher values → less visible
  • Meshes: Select the meshes you want this outline applied to.
    • A mesh can only have one outline parameter.
    • You can create multiple outline parameters for different meshes.

3 Save your .xc and try in game

4. Fix Lighting/Appearance Issues

Sometimes outlines may look bad due to lighting. To fix this:

  1. Select the faces that look strange.
  2. Delete the faces (duplicates will remain).
  3. Reverse the normals of these faces.

Example: If the mouth looks wrong, remove duplicate faces from the mouth and reverse their normals.
If this does not solve the issue, move the faces to another mesh.
