cooool....

It does not work for me. I use this wdl script. The level texture in WED is named "floor1.bmp":

bmap detail_floor1, <floor1.tga>;

function init_detail_mapping
{
bmap_to_mipmap(mtl.skin1);
}

material floor1
{
event=init_detail_mapping;
skin1=detail_floor1;
effect=
"
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;
}
}
";
}

Could someone give a link to a example detail or bumpmap tga file? I think mine is wrong...

What version of gstudio do you have?
For level geometry bump-mapping to work you need to have A6.31.0, and dx9c installed.

Hi

Yes i have A6.31.0 and DX9.0c installed. My PC:
P4 2.4GHz 512RAM
GeF Ti4200
I think this should work...

I played around a bit and now it works! The mistake was:

since I use the new WED feature, giving a path for textures to compile a wad file automatically. The texture in that path is called "bumptest.bmp"

"material bumptest_bmp" instead of "material bumptest".

So for the dot we must give an underscore to work properly (is this not yet documented, conitec?).

So let me get this straight, the texture itself doesn't have a greyscale bump channel? If not, then does the shader create the illusion of depth based on color values in the texture?

I've only used bump maps in pre-rendered work before. So I'm just trying to understand how this all works.

Jim

skin0 is the regular texture, and skin1 holds the normal map...

i think...

at least that's the way it works in 6.22 on models... gonna try 6.31 this evening (fingers crossed)

Here's some info for those that want to know a little more about the shader.

entSkin1 - Level Texture (no lighting in this texture)
entSkin2 - Level Lighting (this gets rendered over the texture using AddSigned)
mtlSkin1 - The normal map. You define this in the material as skin1

The normal map has to be created beforehand, the shader won't generate its own. If you want it to generate its own, you need to add the following function above the material:

Code:

---

function init_textureNormals()

{

  bmap_to_normals(mtl.skin1,2);//convert the skin to a normal map

}

---

And add this into your material definition:
Code:

---

event = init_textureNormals;

---

In this case you MUST still define skin1, but doing it this way- you can simply set a bmap to the texture image, rather than a normal map for it. Keep in mind it is processed faster to use your own normal map than to create it in the engine.

EDIT: @Snake67- all you need to do is replace bmap_to_mipmap with the bmap_to_normals statement here and it should work .

Wow, this works fine .
But how can i use it on models? The old bumpmapping shader doesn't work anymore and i don't know how to get this new one to work on models. Can you tell me what i have to do?
Thank you
