[osg-users] VPB and unusual normals

[Chris Hanson]

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.

Any insight from anyone?
