It's not great... but it may give you a start. You'll have to play with the textures. You can modify it alot... Leave it as is, and/or modify it with some pieces of code from the ones that turn black. Things like the projected texture. Adding another stage with a colormap or envmap.
However, you will not be able to add a lookup into a cubic environment map. The Geforce will not do the dependant texture reads for it.
The pixelshader.1.1 water code I have is not open source yet... sorry.
Code:
bmap water_bump = <water_bump.tga>;
bmap water_spec = <water_spec.tga>;
function mtl_water_func();
function mtl_water_func()
{
mtl.skill1 += time;
mtl.matrix23 = floatd(mtl.skill1,180); // u offset ????? Something changed????
mtl.matrix13 = floatd(mtl.skill1,200); // u offset
}
function mtl_water_init()
{
mat_set(mtl.matrix,matWorld);
mtl.matrix11 = float(4.5);
mtl.matrix22 = float(2.0);
mtl.matrix41 = 0;
mtl.matrix42 = 0;
mtl.matrix43 = 0;
