I get this error when I try to bind the shader:
"spot", "nv", "lv" and "vv" are varying, which are written in the vertex shader and read in the fragment shader.QGLShader::link: "WARNING: vertex shader writes varying 'spot' which is not active.
WARNING: vertex shader writes varying 'nv' which is not active.
WARNING: vertex shader writes varying 'lv' which is not active.
WARNING: vertex shader writes varying 'vv' which is not active.
Did anyone face this issue?
