Avastar-2.0-alpha_3_blender-2-77.zip

We have published an Avastar update that matches to the proposed changes of the avatar definition files from the Bento Project. If you are an Avastar customer then you now find the update in your download folder. Most apparent changes:

  • Sliders no longer useShape Keys
  • Sliders now available in Edit mode
  • New Bento Skeleton definitions

Beware: This is an Alpha release!

Please use the development viewer that was made by Vir Linden to test your meshes in SL

Changes in the definition files

The Eyes

When you weight your custom eyes to the mEye or the mFaceEyeAlt bones, then scaling the eyes with the eye Size appearance slider now also affects the size of the mesh eyes.

bento_scaled_eyes

The Eyelid joints (mFaceEyelid…) have been moved to match the Eye joints. This was made to create more consistent Eyelid animations based on rotations only.

The Eye Size slider introduces a small offset on the mEye bones (grey in the image). We have chosen to not add translation to the eye lid sliders.

In the image you see how the eyelids open/close moves (green) compared to how they would move when placed at the same location as the mEye bones. (left side slider=0, right side slider=100)

Image82

The Eye Spacing slider uses translations on all eye related bones. We have not found any good way to replace this by scaling without distortion (scaling would change the size of the eye sockets and the eye lids).

The Jaw joint (mFaceJaw) was moved to an anatomically more correct location. This was made to provide better movement of the mouth area when opened using only rotation animations.

Image80

Lower Teeth (mFaceTeethLower) now parented to the Jaw bone. this was made to provide anatomically correct behavior.

Note: To get good slider behavior you should weight the lower teeth to the lower teeth bones and the upper teeth to the upper teeth bones. If you decide to weight the teeth to other bones, the slider behavior is not predictable.

Important Tool changes in avastar:

  1. custom meshes no longer create shape keys when sliders are enabled
  2. Sliders now also work when your mesh is in edit mode
  3. The joint position editing is almost ready to use (see note below)
  4. Updated weights for the head mesh. Eye lids now should work much smoother
  5. All recent changes to the skeleton and lad are included

Known issues (to be fixed):

  1. When you create a new Avastar character, then its head reacts to the sliders differently than in SL. But when you create a custom mesh head (even a clone of the Avastar mesh) then it behaves correctly.
  2. The new joint position editor still has difficulties with the bone end points of the leaf bones (bone tips at end of bone chains are handled wrong)
  3. When you edit a mesh (add/remove verts) while sliders are enabled, this can lead to very odd behavior when you change back to object mode. Best is to disable sliders when you attempt to add/remove verts. Moving verts should be ok. Don’t forget to bake changes into the mesh before you leave edit mode.
  4. when you disable/enable the sliders it can happen that the eyes pop out of the face. When that happens, then in most cases it is sufficient to enable the sliders again. Then the eyes snap back where they belong.

Note for joint position editing:

The joint position editor is not strictly necessary to define joint offsets. For now an alternative way is :

  • disable sliders and keep them disabled!
  • edit your skeleton as needed
  • When you export, then export without joint positions. This will export the skeleton as it is. SL figures out on its own which bones need to get joint offsets.

When the joint position editor is ready it will become possible to use the sliders AND define joint positions.
