IK Handles and LookAt Constraints from Max

[EnvisMJ]

I'm trying to control an excavator that I have brought into Vizard from 3DS Max.

ex. http://img.diytrade.com/cdimg/510999...or_SC220_7.jpg

The boom is controlled by an IK handle, and the pistons are controlled by LookAt Constraints.

I can see the node within the excavator's IVE file for the IK handle, but when I move it, the boom does not move.

Do I need to do something special to export these constraints from Max, or does Vizard just not support them?

Thanks,
MJ
