Is there a way to reset the material values (glMaterialfv()) back to default? If not, does anyone know the default values for each GL_AMBIENT, GL_DIFFUSE, GL_EMISSION, GL_SHININESS and GL_SPECULAR so that I can do it manually? Thanks.

From the Blue Book:

GL_AMBIENT 	 	The default ambient reflectance for both front- and back-facing materials is (0.2, 0.2, 0.2, 1.0).GL_DIFFUSE 	 	The default diffuse reflectance for both front- and back-facing materials is (0.8, 0.8, 0.8, 1.0).GL_SPECULAR 	 	The default specular reflectance for both front- and back-facing materials is (0.0, 0.0, 0.0, 1.0).GL_EMISSION 	 	The default emission intensity for both front- and back-facing materials is (0.0, 0.0, 0.0, 1.0).GL_SHININESS 	 	The default specular exponent for both front- and back-facing materials is 0.

Thanks.
I would have looked in the Blue Book had I not taken it back to the library a few hours before asking the question. I should probably buy it really.

I have a html version of it and The Red Book, would you like me to e-mail you them (about 8Mb rar'd)?

Thanks for the offer but I've got too much other coursework to do before I'll have time to play around with opengl again and by that time I should be able to afford the books.

No problems mate ;)
