Hello,

I read the tutorials about shader and tried to change it
so I can use it to make dot3 Mapping on level-blocks.
I just can't make it work...
The engine says: unexpected token "~"

Code:

---

bmap dot_3map = <dot_3.bmp>;

material dot_3
{

	skin3 = dot_3map;	

	effect
	"	texture entSkin1;	// block texture
		texture entSkin2;	// shadow texture
		
		texture mtlSkin3; 	// the bump map
		
		technique bump_dot3
			{
				pass P0
				{
					Texture~[0] = <entSkin1>;
					Texture~[1] = <entSkin2>;
					~TextureFactor = <mtlSkill3>;

					ColorArg1~[0] = Texture; // stage 0 = bumpmap
					ColorOp~[0] = DotProduct3;
					ColorArg2~[0] = TFactor;
					ColorArg1~[1] = Texture; // stage 1 - skin texture
					ColorOp~[1] = ~AddSigned;
					ColorArg2~[1] = Current;
					ColorArg1~[2] = Diffuse; // stage 2 - lighting
					ColorOp~[2] = Modulate2x;
					ColorArg2~[2] = Current;
				}
			}

	";
}

---

Can someone please help me?

delete all the "~"

Thank you,
but it still doesn't work.

I think the whole "pass P0" is wrong. It was made for
models and not for level textures.

Code:

---

bmap dot_3map = <dot_3.bmp>;

material dot_3
{

	skin3 = dot_3map;	

	effect
	"	texture entSkin1;	// block texture
		texture entSkin2;	// shadow texture
		dword mtlSkill1;	// a variable?
		texture mtlSkin3; 	// the bump map
				
		technique bump_dot3
			{
				pass P0
				{
					Texture[0] = <entSkin1>;
					Texture[1] = <entSkin2>;
					TextureFactor = <mtlSkill1>;

					ColorArg1[0] = Texture; // stage 0 = bumpmap
					ColorOp[0] = DotProduct3;
					ColorArg2[0] = TFactor;
					ColorArg1[1] = Texture; // stage 1 - skin texture
					ColorOp[1] = AddSigned;
					ColorArg2[1] = Current;
					ColorArg1[2] = Diffuse; // stage 2 - lighting
					ColorOp[2] = Modulate2x;
					ColorArg2[2] = Current;
				}
			}

	";
}

hm, i have no idea where's the mistake, but i can provide some code which actually works on level geometry ( i assume you know how to use apply them via d3d_automaterial):

Code:

---

matrix matWorldViewProj;
matrix matWorld;

texture mtlSkin1;
texture entSkin1;
texture entSkin2;
vector vecLight;

technique dot3map
{
pass p0
{
Texture[0] = <mtlSkin1>;
Texture[1] = <entSkin2>;
Texture[2] = <entSkin1>;
TextureFactor = 0xFFFFFFFF;

COLOROP[0] = DotProduct3;
COLORARG1[0] = Texture;
COLORARG2[0] = TFactor;
TexCoordIndex[0] = 1;

COLOROP[1] = Modulate;
COLORARG1[1] = Texture;
COLORARG2[1] = Current;
TexCoordIndex[1] = 0;

magFilter[2]=Linear;
minFilter[2]=Linear;
mipFilter[2]=Linear;
COLOROP[2] = AddSigned;
COLORARG1[2] = Texture;
COLORARG2[2] = Current;
TexCoordIndex[2] = 1;
}
}

Code:

Would anyone have an idea of how to have either of these shaders react to dynamic lights? Say 3 lights? I've tried both shaders and they work well on level blocks and the performance is pretty good (at least on my machine). The one problem is that when using these shaders, dynamic lights no longer react on surfaces where these shaders are applied. The lighting from standard wed lights looks great though.
