Dank dir Ello, war ein guter Tip. Jetz kann ich wenigstens schon ein dx8 von einem dx9 shader unterscheiden.
Habe alle Fehler so beseitigen können, das wird mir sicher noch nützlich sein. Danke nochmals.
Was ich jetzt nicht verstehe ist warum mein Grass einfach nur schwarz dargestellt wird und es keine Bewegung hat.
Hier noch der code:
Code:
///////////////////////////////////
// grass.wdl
bind <grass.fx>;
bmap grass_bild = <grass02.tga>;
/*
function makemips
{
bmap_to_mipmap(mtl.Skin1);
}
*/
material mat_grass
{
Skin1 = grass_bild;
//event = makemips;
}
Action grass_wave
{
fps_max = 60;
effect_load(mat_grass, "grass.fx");
wait(1);
my.material = mat_grass;
}
und hier die fx datei:

Irgendwie denke ich es könnte an den vertexShaderConstants liegen...irgendjemand ne Idee in welcher Richtung ich suchen muss?
cheers
