Thanks, Redphoenix, but in my region I am paying internet usage by the megabyte  - that massive compilation costs a lot!!  That set of shaders in your download library, Slin, look awesome with dynamic lights, but again, they don't react properly to the sun. They are completely black where they are not lit by the sun or dynamic light, and the ambient lighting does nothing for that. I'm sorry about my shader programming ignorance, but this one sunlight bumpmapping shader would really add some spice to my game. If I could have a post, with imbedded code, that would be great  Thanks, all you shader pros!

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.

the shader now uses another pass and thus supports 7 lights + sun light. it is not very optimized from what i can see... you could reuse much of the code above, but making it faster and shorter is another thing... i haven't tested it but i think it should work. if not, just post the error message you get and i'll have a look at it. joey.
