Notepad is probably the best thing to use, but to program shaders your going to need to know HSL or something, definitly not and easy programming language. You should also look into FX files and how they work.
well, its easier than c-script due to it has less instructions. however, the mathematics behind are the most difficulty with it - thats what i think about it
btw, i emailed them, but didnt get response yet... :P
From what I understand from the above posts, I copied the code into notepad and saved it as a .fx file. Can I email it to you so you can test it or something? Ive only got A6 standard at the moment.
