Hi Nilton,
Neither osg::BoundingBox or osg::BoundingSphere will be sufficient for
the purpose of collision detection against polygon wall geometries,
these bounding volumes are just suitable for very coarse grained
intersections tests like required for culling.

osgExp expects specular in range 0...1000, that is range you can set in 3ds max
for specular intensity. It's looks different in 3ds max then in osg though.

Well, I'd like to avoid writing files on the local system (as I'm running

Hi Sergey,
osgExp expects specular in range 0...1000, that is range you can set in 3ds max
for specular intensity. It's looks different in 3ds max then in osg though.
OK, that explains it, I thought the max was 100. I'll adjust my shaders
so the result looks the same in Max and in OSG.
