This page is dedicated for creating a proposal that can act as a starting point for OpenSimulator avatars. The idea is to create one or more base models with blender which can be used as basis for Avatar modeling.

Avatar is one of the most important immersion factors. To help the community to start creating high quality avatars we need your help to get the effort started. If you have any improvement ideas or corrections please fix this page. You can join the project by registering to the following discussion group and requesting for content repository commit rights: Open Content for Metaverse

Nice tutorials about using Blender to do avatar poses and animations. The biped model used in these tutorials is available as basis for further work at the model repository:

Oh and we want to figure out how to play these with our avies: CMU Graphics Lab Motion Capture Database

More bvh animations can be made with Qavimator.

Make Human is a project which can be used to create human avatar models. Combination of non linden based clients and OpenSimulator could support MakeHuman avatars directly: MakeHuman

[edit] Model Repository

Model repository is available as google project:

http://code.google.com/p/open-content-for-metaverse/source/browse/#svn/trunk/Models/Avatars/Biped/

  • I added Nathan Vegdahl's public domain biped.blend as starting point for Avatar Modeling. - Tommi
    • Bone structure can be studied under overwiew/current scene/rig/armature
    • IK stands for inverse kinematics.
    • GZM stands for gizmo and refers to meshes which are helper clases for bone visualization.

[edit] Best Practices

  • Rational polygon count.
  • Use the default bone structure or update the default bone structure.

[edit] Default Bone Structure

If you need more bones to achieve good result feel free to insert them here. Not all bones are necessarily needed and custom bones may be added to models. Viewers are more likely to support steering default bones.

   LeftThigh-LeftCalf-LeftFoot-LeftToe0-LeftToe0Nub (Connected to Spine)
   RightThigh-RightCalf-RightFoot-RightToe0-RightToe0Nub (Connected to Spine)

[edit] TODO

This task list contains tasks which need doing. Please add more tasks and claim tasks for yourself. If this list gets actively used we will probably move it to the google project issue tracking.

  • Edit the biped.blend to follow the bone structure naming convention and possibly add missing bones. It is also possible to edit the default bone structure to better reflect the biped.blend if it is more reasonable. (Task not claimed.)

[edit] Exporting from Blender to OpenSimulator

The current proposal is that Blender files (.blend) will be exported to Collada format and stored as binary assets to OpenSimulator. Collada files can then be converted by client views or Viewers to browser specific formats.
