HI @jevlin – Your frustration is shared by everyone who’s ever journeyed into computer graphics. I’ve been there and still go through it on occasion. CG is very difficult. Period. That’s to say, go easy on yourself. This stuff isn’t something that can be truly learned over night; not even from one course. I just published an article about 5 lessons that I learned over the course of 10 years.
With that said…. I don’t really see much difference between my shader and yours. Your mailbox is reading like work brass/metal which is the goal. So…can you help me understand what exactly aren’t you happy with?
