[osg-users] MacOSX/Core Profile: Attribute aliasing behavior ?

[Julien Valentin]

Hi
In core context, osg wraps deprecated arrays (Vertex,Normal) to vertex array attributes that's why a few are reserved for this purpose (VertexArrayAttrib 0 to 5 If i remember).
It can appears wrong but it's the choice made to preserve both gl compatibility and osg semantic.
Cheers
