Hi Daniel, you are right, with BIND_OVERALL and just one element in the array, OSG should apply the single attribute to all vertices of the geometry. You can check this behavior in Geometry.cpp searching for BIND_OVERALL. Also there is the createTexturedQuadGeometry() function which does setup a geometry like you want, so check it out if you do it the same way. If it does not work, try to put a breakpoint into Geometry.cpp and debug to see what happens.
As you say, setting Uniforms requires a state change, while with an attribute the rendering is done at the GPU completely. Thank you!
