Hi ya shadermen!
I would like to apply sunlight (like in the template mutitexterrainshader) on this terrainmultitextureshader by Thorsten Kunze...As usual, I don't know how
Is someone could add working sunlight to the code, I'll gladly offer him some unreleased Trees in exchange!
You can also download this shader with a testlevel at Kunzes website
terrainshader-testlevel Code:
// multirgb.wdl
// entSkin1 Texture Base
// entSkin2 Texture Layer Red
bmap tex1 = <gras.bmp>; // RGB Mask
bmap tex4 = <road.bmp>; // Texture Layer Green
bmap tex5 = <sand.bmp>; // Texture Layer Blue
bmap tex6 = <detailmap.tga>; // DetailMap
function multirgb_roughness() {
bmap_to_mipmap(mtl.Skin1);
bmap_to_mipmap(mtl.Skin2);
bmap_to_mipmap(mtl.Skin3);
bmap_to_mipmap(mtl.Skin4);
}
material multirgb {
flags = tangent;
skin1 = tex1;
skin2 = tex4;
skin3 = tex5;
skin4 = tex6;
event=multirgb_roughness;
