Help with animating my Machine Gun Operator

[jib]

I am trying to add an animated model of a soilder to my DSHK

I have added the Soldier mesh and given him bones and skinned the model in 3dsMax.

 

But I'm having difficulty with getting the animation to look right.

 

On the animation of arg 0 (the turret turning) the animation is fine the solider spins with the gun, it is the combination of arg 0 and 1 I'm having trouble with.

 

I am having trouble getting the soldiers feet to stay on the ground during the animation of arg 1. The soldiers whole body flies up into the air when the gun tilts.

 

I have tried adding a motion constraint which is a circle around the gun and binding a dummy box to it which is linked to the skeletons feet.

 

This seems works great for arg 0 (rotation) and his feet then stay on the ground but the constrained dummy is linked to a point on the gun and when the tilts the dummy box circulates around the constraint line, when I need it to stay still.

 

If there is a way to set different constraints on the animation when different args are selected that would really help.

 

Does anyone have any ideas on a combination of dummies, constraints and links which would provide a natural looking soldier animation?

 

If I haven't explained it clearly I will upload a screen shoots or video of my problem when I get home.

 

Edit: Uploaded screen shots

 

Rotation is fine

 

I cannot get tilt animation to work, with his feet staying on the ground and the linked bones moving naturally.

 

Is there any way for an arg to effect 2 objects?

 

Or am i going about this the wrong way?

 

I have attached the 3dmax file if anyone wants to have a look at it.
