Hi Thomas,
I dont know in which state is the 3ds max osg exporter. I use the osg
exporter for blender, i maintain it and use it. Examples from osg-data
comes from blender so it's a working path and the one i use.
In futur there will be a collada that will support osgAnimation but not
yet ready.

I don't know how to appreciate that, Thanks.
When I started how to use osg it was really difficult because there was no any

Does your algorithm determine the "height" of your flattend area itself by the

Robert,
My system has cmake 2.6.1 installed. I initially found the QT_USE_WEBKIT in
cmake-2.6.1/Modules/FindQt4.cmake and it seemed to work. After a bit more
searching I found QT_QTWEBKIT_FOUND works as well and is more consistent with
the rest of the cmake variables in OSG's CMakeLists.txt.

Hi Ryan,
I sounds like the lack of a readRefFontFile() is a potential problem.
In the case of include/osgDB/ReadFile there are readRefNodeFile() etc.
functions that pass back a ref_ptr<> rather than a C pointer, and are
all safer in multi-thread situations where object cache is in play.
