(Assigning Group): WORD - Length of animation name including the 00 ending byte Animation name BYTE - 00 (end of animation name) WORD Material Index Number WORD X Adjustment WORD Y Adjustment WORD Z Adjustment ...
The other theory on the animation group besides it containing actual data relating to moving the object is the following: "Textures are referenced by the Materials tab and then related to the correct 3D groupings via the Anim(ation)? tab; this contains the material number as specified in the materials tab and the X,Y,Z group axis it applies to (pretty much stays with it's own groupings). In an example, frame 4 is a road texture and (x,y,z)(4,4,4) is the group for the road overpass bridge. " This data provided via krelf
