This sounds like a center-point / parent problem. I recommend to clear parent
relationship for your minifig components (keeping the transform). After import,
all bricks are a child of the surrounding .ldr file, which is a empty object at
(0,0,0). Use the "outliner" window (View->Outliner) to visualize the parent
relationship for all scenes, objects, materials etc. Afterwards, you can regroup
the objects with the body of the mifi as your parent. This should resolve the
rotation weirdness:)
I have used NLAnimation for my mifis by attaching an armature (8 bones
[Head,Body,Lleg,RLeg,LArm,RArm,Lhand,Rhand) to a joined mifi-mesh. The vertices
of the mesh where grouped (Head,Body,..) use the same names for the vertex
groups and the bones (this enables automatic matching from bones to
vertex-groups). I have put a sample blender file on
http://homepage.mac.com/carstenm
(a single mifi walking circles while moving its head and one arm) not very
fancy.

| (...) I downloaded this file but it makes my version (2.37a) of Blender crash. Did you use a newer version to make this file? Thanks, Brian Durney (21 years ago, 15-Mar-06, to lugnet.cad)
