This script exports a Blender mesh with armature to DirectX 8's text file
format.

Usage:

1) There should be only one mesh and one armature in the scene;

2) Before parenting set:<br>
   a) Armature and mesh must have the same origin location
(in the 3d View press N (menu Object->"Transform Properties") for both and set
same LocX, LocY and LocZ);<br>
   b) Armature and mesh must have the same rotation
(select them and press Ctrl + A);

3) Set the number of the animation frames to export;

4) Read warnings (if any) in console.

Notes:<br>
    Check author's site or the elYsiun forum for a new beta version of the
DX exporter.
