help in battlefield example
 

I am beginner with Vizard and am trying to understand how can I import my own environment into vizard and then to change some characteristics. One suggestion was to export my environment to .ive through OSG exporter, unfortunately I have struggled to install OSG exporter for Max and I have got this message “openthreadsWin32.dll was not found.”
As well as I am struggling to use battlefield example in Max2009 (as my own environment) with vizard but I have a problem with the following points :
To use getChild()
To import new image and texture it with the environment.
Avatar walks probably on the environment.

I believe when I can control the environment, all the points aforementioned will be solved.
Any suggestion would be really appreciated.
Thanks
