I wanted to write a message about strange message from Ogre.log, but now I see what it is, but let me say I don't like that behavior of ogre3d :
Hello what happened to command parameter light_specular_colour ? I keep getting errors like

That way I got the error above, but shouldn't such a mistake be just a warning or not reported at all ? That way I loose other errors information... why does the GLSL compiler or material compiler ( or both ... ) behave like that --- reporting ONLY the first error ? ..... Whose choice it was ? hmm
?
