[osg-users] Regarding Converting 3ds Max file in OSG format

[HITESH Singhal]

I was asking all that because I'm working on a software named VIZARD and it
supports only OSG files. I have no option using any file other then OSG. So
where can I find 3d Shopping Mall model in osg files directly. Any
suggestion?
