Here is some code for blending (5) textures using the fixed-function pipe.

Code:


///////////////////////////////////
//  ffp5tex_action.wdl
//

bind <ffp5tex.fx>;

//var terrain_chunk = 128; 

// Additional FFP blendmaps
//


bmap sand = <sand.tga>;
bmap grass = <grass.tga>;
bmap road = <road.tga>;
bmap stone = <stone.tga>;


function makemips {
bmap_to_mipmap(mtl.Skin1);
bmap_to_mipmap(mtl.Skin2);
bmap_to_mipmap(mtl.Skin3);
bmap_to_mipmap(mtl.Skin4);
}


material mat_ffp5terrain{


Skin1 = sand;
Skin2 = grass;
Skin3 = road;
Skin4 = stone;

event = makemips;

}



Action Terrain {
fps_max = 60; 
effect_load(mat_ffp5terrain, "ffp5tex.fx");
wait(1);
my.material = mat_ffp5terrain;
}

Code:
