ok but i mean,m you know all the formulas to achive falloff, gradient, noise, etc etc, that reflectio refraction, so easly, than a visual editor, like for example mental mil.
probably you should know this math for writing shaders. these editors are ok if you want to draft something new. i've also used fx composer just to look at the assembly output of the shaders, but these tools can never replace handwritten shader code.
@impaler: when you post your code we can have a look at it and correct it.
