LOD per individual mesh??

[Gladsomebeast]

Actualy, Vizard does not currently support level of detail on Cal3d models.

You could also be getting poor frame rates if your avatars are exicuting animations. This is because the computer must operate on each vertex of the avatar's mesh, each time it animates the avatar. If this is the problem, changing the avatar's <VizAvatar>.updaterate() fuction should help.
