Caging

Caging is the process of updating the cage mesh component of your avatar character. To allow your character to correctly wear layered clothing and accessories, you must update the default template cage mesh object to match the sculpting changes you made to your custom character.

Since this tutorial only applies modeling changes to the head, the caging instructions below only apply to the Head_OuterCage object. If you make geometry changes to other parts of the character, you must also adjust those specific _OuterCage objects to match your sculpting changes.

To begin caging your character:

  1. Starting from the Layout Tab, hide everything in the Outliner except the Head_OuterCage and the Head_Geo objects.

  2. With the Head_OuterCage selected, navigate to Object Properties > Viewport Display and set the Display As to Wire. Toggle this setting back to Solid when you are finished.

  3. Click on the Head_OuterCage object and switch to Edit Mode.

  4. Enable X-Axis symmetry and Topology Mirror to ensure you are making symmetrical vertex changes to your cage.

  5. Switch to Edit Mode.

  6. Using the Grab tool (G), click and grab parts of the cage mesh and align it to fit tightly over the goblin head mesh. Keep the following in mind:

    1. Never delete any of the cage vertices. Missing vertices can cause errors and issues with equipping clothing accessories.

    2. If editing the base of your head cage, ensure that the base of the Head cage aligns with the top of the UpperTorso cage.

    3. In different Select modes, hold Shift and click multiple vertices/edges/faces to select and edit the geometry.

    4. You can verify a tight fit by grabbing vertices and moving them into the Head_Geo mesh to check where the meshes intersect and moving the cage vertices until the cage mesh just covers the head mesh.

    5. Toggle visibility on your different mesh objects to improve visibility and access to vertices.

    6. After the wireframe is tightly fitted over the head mesh, set the Display As back to Solid and spot check and fix any intersecting vertices.

Your final product should feature a cage mesh that sits directly over the head mesh without any of the Head_Geo geometry intersecting through the solid sections of the cage.
