|
|
Since i cant code all these new function alone,
|
|
i really need help to find the best way to provide
|
|
GRRLIB functions to all these new effets in this demo.
|
|
With the help of the doc you can try also to find how it works,
|
|
for exemple i didnt succes fully coded a specular position and direction....
|
|
So i repeat i need HELP !!! ;)
