The .glsl plugin does now set the shader type automatically based on whether the .frag or .vert extension is used. The code in question is (from src/osgPlugins/glsl/ReaderWriterGLSL.cpp: if (shader->getType() == osg::Shader::UNDEFINED) { // set type based on filename extension, where possible if (ext == "frag") shader->setType(osg::Shader::FRAGMENT); if (ext == "vert") shader->setType(osg::Shader::VERTEX); } I haven't merged this change into the OSG-2.8 branch, which is probably why you don't see the warning. It would be odd to load a .vert shader and then set it to be a FRAGMENT shader type so this suggests a bug lurking in osgOcean or the resources.
