animate character (ogre): holding feet on ground

[Akrisios]

Hello,

I got my model into Ogre (a graphics engine) via makehuman -> mhx (game rig) -> Blender -> blender2ogre (exporter) -> ogre. I then have a Kinect and use OpenNI to identify users. Some programming has been done to make my model mirror user's actions. Every bone rotates the right way, so there's no problem with mathmatics. The issue is: My character stands on ground, I can move my arms and even my torso and it looks good - but If I crouch, my model stays in the air and draws up knees (looks like jumping).
How do I force my model to squat down? Is there any option to activate while exporting from makehuman that is holding feet on ground? Is it a Blender issue? An Ogre's?

Since the game rig is a pure FK rig, you need to translate the Root bone (in the pelvis area) down. Does the pose look OK in Blender?
