I´ve got this error:

Malfunction W1550

Error in Effect:
mat_terrain_multitexture(78):error X3000:syntax error:unexpected integer constant

The debug syntax check found no error, can anybody help??

After you do all the above corrections.... then for this one;
Try correction in this line: (get rid of the last zero)
vertexShaderConstant[65]={20.0f,15.0f,0.0f, 0.0f0 };

if you still get the error, try changing this line:
vertexShaderConstant[64]=<vecSkill41>;

to something like:
vertexShaderConstant[64]={20.0f,15.0f,0.0f,0.0f};

If it goes away, then you know where to focus attention.

hi,i modify the multitexture shader from wiki and follow the advise from Steempipe. The shader finishly work in DX9 version.
here is the code:



material mtl_multitexture

effect=

texture entSkin1;
texture entSkin2;
texture entSkin3;
texture entSkin4;

{
pass p0
{

Texture[1]=<entSkin3>; // colormap2
Texture[2]=<entSkin2>; // colormap3
Texture[3]=<entSkin4>; // macromap

};


}
}
technique fallback { pass p0 { } }
";
}

action terrain

my.skill42=float(20);
my.skill43=float(5);

}

lekboon: Tested this code it works great thanks to all contributors, a couple questions or request rather please. Dynamic lighting is not working on the terrain, also would it be possible to add 1 or 2 more textures to the blending?

I have no only one texture, no multitexturing. I have an macromap and three textures. What made I wrong or have i forget??

yeah lekboon you rocks!

thanks alot to everybody!
