What is Fitted Mesh?

Fitted Mesh is a technique in which an avatar's collision bones are used to add further deformation detail to an avatar or clothing. The benefit of this technique is that it allows Mesh clothing and avatars to be adjusted using an avatar's Body Shape sliders in the Appearance Editor. This results in clothing that can adjust and fit to your avatar's own personal body shape and style.

For content creators, the key difference between a Fitted Mesh skeleton and the previous standard skeleton is that a Fitted Mesh skeleton has more bones. The rigging workflow is the same except that the additional collision bones are also included in the skinning/binding process. Note that unlike the mBones, you do not need to include all of the collision bones, rather only the ones you wish to use.

KBtip2.png Tip: For the best results and to avoid unsightly clipping, you should use alpha masks to hide areas covered by mesh on your avatar.

Rigging using the Fitted Mesh technique

  1. Download one of the skeleton files.
  2. Follow one of the many tutorials for rigging avatars in your modeling program of choice.
  3. Export your new rigged mesh from your modeling program of choice:
  4. Import the rigged mesh to Second Life and wear the model, as described in Uploading an wearing a rigged mesh.
