hi aye Jonathan,
Just wondering, got to the quiz for the first section tonight, one question came up for how to implement the Specular lighting model. Cant remember that being covered as yet, had another scan through but couldnt see a reference to it. would it be a missplaced question relating to surface shaders further down the line? thought I would ask :)
Hey Darren, yes you're right. When I wrote the quiz I had written it after completing the course. I may need to make multiple quizzes for each section. I'll modify that first quiz to only apply to the first chapter. Thanks for letting me know!
