'VizChild' object has no attribute 'state'

[nat_bor]

hello

I made a thin avatar overweight in 3ds max and I exported this avatar with the osg exporter (.ive) to vizard.
The avatar is now in Vizard but he doesn't move.
I can't add a state (vizard complete characters) to the avatar (walking, eating...). There is always written: 'VizChild' object has no attribute 'state'.
Is anybody here who knows how to animate the avatar in vizard or knows a better way to make a complete character overweight, export it to vizard and animate it there?

I really need to manage this problem

Please help me

Thank you
