Hi Ulrich,
(The model and lightsource are a shared graph, right?)
Yes, that's right.
With regards to the different lighting, how is your model
tessellated? If it's coarsely tessellated and/or you're using face
normals then the lighting calculation might only be done on the corner
vertices an

Hi Simon,
Thanks for the promising link, but I don't think I'm misusing the
projection matrix. I calculate the left, right, top and bottom values
and set the projection matrix via osg::Camera's
setProjectionMatrixAsFrustum. The view matrix is set with
setViewMatrixAsLookAt using the head-trac

Just a quick guess, but are you putting rotation into your left &
right projection matrices?
If so that's what's mucking up your lighting:

Hi,
