Hi David,

I scale the PositionAttitudeTransform by (5,5,5) for example, because my model

small, but then the lighting isnt sufficient. Is there a way to scale the

Hope you understand my problem if you need more info, Ill be glad to give it,
thanks in
advance for the help! David
This is a FAQ. When you scale a model you scale the normals as well which
affects lighting.
You need to tell GL to re-normalize the normals by setting the GL_NORMALIZE or
GL_RESCALE_NORMAL modes.
Have a look at the comment in the osg/Transform header file.
Cheers,
