Hi, 
  
Because Leadwerks use only bones to animate 3D models, I created a simple scene is Blender with 2 disconnected bones that allow me to translate an object. After exporting it to an .mdl file, importing it into LE and open the model editor: the animation is present but my object doesn't move. 
  
Is Leadwerks need bones to be connected together to be animated?
