Got 3dmax7: what do I need to do custom animations/facial expressions ?

I already have 3dmax 7 and am getting interesting into creating custom animations, custom facial expressions and custom avatars (opensim and the likes).

What do I need to do this ? (links, tutorials, plugins, ...)

A) Custom animations with 3dmax

B) Custom facial animations with ???

C) Custom avatars with 3dmax

A) The oldest version of Max that I know of that the community has developed Second Live animation capability for is 3ds Max 8. Abu Nasu developed a Maxscript which might work in 7, but I believe the required file that has the animation armature was made in Max 8.

B) Facial animations are accessed through in-engine scripting. There is no mechanism for external influence of the face, hands, or morph targets.

C) Prim composer http://liferain.com/downloads/primcomposer/ is a 3ds Max environment for SL compatible offline building. The issue with offline building for custom avatars, regardless of the application, is that of matching up the offline build with the in-engine avatar mesh. Judicious use of Maxproxy application available with the Prim Composer download in conjunction with Open Sim and a viewer that can export the Avatar settings can make the task of going back and forth with adjustments a bit easier.
