Hello Paul, In OpenGL I have to define the varying variables for the transform feedback between the compiling and linking of the shader program.
glTransformFeedbackVaryings(programHandle, 1, varyings, GL_SEPARATE_ATTRIBS); How can I do this in OSG? Additinally I use osg 2.8.4 from the Fedora repository.
