Hello again, My program outputs the maximum vertices output for a geometry shader as follows:
GLint maxGeomVerts; glGetIntegerv(GL_MAX_GEOMETRY_OUTPUT_VERTICES_EXT, &maxGeomVerts); osg::notify(osg::NOTICE) << "Max geometry shader output vertices: " << maxGeomVerts << std::endl; Interestingly, building with osg2.4 yields 1024, whereas the exact same program built with osg2.6 yields 0. Is this a bug ? regards, Bill
