Why does it say "Terrain material for an unlimited number of terrain textures"? This makes no sense!
//////////////////////////////////////////////////////////////////////
// terraintex.fx
// Terrain material for an unlimited number of terrain textures
// Tiled texture on RGB, mask on alpha
Texture entSkin1; // basic tiled terrain texture
Texture LightMap; // lightmap created by the map compiler
bool PASS_SOLID; // enforce rendering on the solid pass
bool AUTORELOAD;
//////////////////////////////////////////////////////////////////////
// technique without lightmap
technique terraintex
{
pass multi_repeat11
{
ZWriteEnable = True;
AlphaBlendEnable = True;
SrcBlend = SrcAlpha;
DestBlend = InvSrcAlpha;
Texture[0] = <entSkin1>;
TexCoordIndex[0] = 0;
AlphaOp[0] = SelectArg1;
AlphaArg1[0] = Texture;
Texture[1] = <entSkin1>;
TexCoordIndex[1] = 1;
ColorArg1[1] = Texture;
ColorArg2[1]= Diffuse;
ColorOp[1] = Modulate2x;
AlphaArg1[1] = Current;
AlphaOp[1] = SelectArg1;
ColorOp[2] = Disable;
AlphaOp[2] = Disable;
}
}
// technique with lightmap
technique terraintex_lm
{
pass multi_repeat11
{
ZWriteEnable = True;
AlphaBlendEnable = True;
SrcBlend = SrcAlpha;
DestBlend = InvSrcAlpha;
Texture[0] = <entSkin1>;
TexCoordIndex[0] = 0;
AlphaOp[0] = SelectArg1;
AlphaArg1[0] = Texture;
Texture[1] = <LightMap>;
TexCoordIndex[1] = 0;
ColorArg1[1] = Texture;
ColorArg2[1]= Diffuse;
ColorOp[1] = AddSigned;
AlphaArg1[1] = Current;
AlphaOp[1] = SelectArg1;
Texture[2] = <entSkin1>;
TexCoordIndex[2] = 1;
ColorArg1[2] = Texture;
ColorArg2[2]= Current;
ColorOp[2] = Modulate2x;
AlphaArg1[2] = Current;
AlphaOp[2] = SelectArg1;
ColorOp[3] = Disable;
AlphaOp[3] = Disable;
}
}
// fallback if nothing works
technique fallback { pass one { } }

From the shader section of the manual:
Passes can have arbitrary names, with the following exception (A7.60): If the first pass name contains the character sequence "_repeat", the pass is repeated for every skin of the model. After each pass the skins assigned to entSkin1..entSkin3 are incremented by 1. So if the model has 5 skins, the pass is repeated 5 times, with entSkin1 set to the model's first, second, third, fourth, and fifth skin in succession. This special method can be used to render an arbitrary number of skins, for instance for multitexture terrain with 4 or more textures.

replace the "lightmap" texture with another bitmap. You must define a BMAP* and use the same name + _bmap in the shader code. Example: in the script:
BMAP* lightmap123 = "lightmap123.tga";
in the shader:
texture lightmap123_bmap;
...
...
texture[1] = <lightmap123_bmap>;
...
...

Hello, I also have a problem with that Shader.
I created a terrain with a skin (DDS with complete white Alpha channel). I only need a terrain with a grass texture. Without the shader it's too diffuse.
Are there any tutorials? I've already read the infos in the manual.

...but I miss something like detail_size...
You must set detail_size before loading the terrain

If you only use ONE texture, you don't need that shader at all.

What kind of problems? If you mean the detail_size, set it BEFORE the terrain is loaded. If you mean the blending of the textures, look in the manual. But i would not recommend this shader anyway, because it's very ineffective. Every texture is rendered in a seperate pass!
