Hallo,
Vor einer Weile gab mir Oliver2S einen Multitexturing Shader. Er soll angeblich super laufen, bei mir gibt es jedoch ein Problem: Die Texturen werden zugleich als Alphamaps verwendet. Die eigentlichen Alphamaps nehmen keinen Einfluss auf den Shader.
(Die Texturen sind als externe Dateien gespeichert, die Blendmaps als Entity Skins 1-3, die 4.Skin ist eine Shadowmap)
Code:
BMAP detail1_bmp = "tex3.tga";
BMAP detail2_bmp = "tex4.tga";
BMAP detail3_bmp = "tex1.tga";
BMAP detail4_bmp = "tex2.tga";
FUNCTION mtl_terraintex_init()
{
mtl.matrix11 = float(27); // default u scale
mtl.matrix22 = float(27); // default v scale
bmap_to_mipmap(mtl.skin1);
bmap_to_mipmap(mtl.skin2);
bmap_to_mipmap(mtl.skin3);
bmap_to_mipmap(mtl.skin4);
}
MATERIAL mat_ffp_multitex
{
event = mtl_terraintex_init;
skin1 = detail1_bmp; //Textur 1
skin2 = detail2_bmp; //Textur 2
skin3 = detail3_bmp; //Textur 3
skin4 = detail4_bmp; //Textur 4

TEXTURE entSkin1; //Blendmap1
TEXTURE entSkin2; //Blendmap1
TEXTURE entSkin3; //Blendmap1
TEXTURE entSkin4; //Shadowmap

TEXTURE mtlSkin2;
TEXTURE mtlSkin3;
TEXTURE mtlSkin4;

An der Graka kanns doch nicht liegen, dass die falschen Texturen als Blendmaps verwendet werden?!
Bitte helft mir weiter,
