Are there any circumstances where VPB is known to not produce sensible vertex normals? Did a build of some terrain with VPB recently, and I haven't used it a lot because most of my customers rely on osgEarth for any non-trivial Earth models. The resulting model loaded and ran ok and the geometry and texture maps seemed fine, but when using the per-vertex normals to perform shininess rendering of ocean surfaces, the normals appear peculiar and non-continuous across tile boundaries.
I don't recall needing to do anything special for VPB normals, but honestly, my memory might not be serving me well.
