Code:
// the following code creates a material that adds DOT3 bumpmapping
// to a model
bmap reptile = <scales.tga>;
material mat_bump
{
skin2 = reptile; // set a reptile skin
scale1 = 0.2; // factor for the skin scale at stage 0
// define a material effect string
effect = "
// declare the used textures and variables
texture entSkin1; // the entity skin
texture mtlSkin2; // the bump map
dword mtlSkill1; // the light vector
// default technique
technique bump_dot3
{
pass P0
{
// set texture stage states
Texture[0] = <mtlSkin2>;
Texture[1] = <entSkin1>;
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;
}
}
// fallback technique for devices that do not support bumpmapping
technique fallback
{
pass P0
{
// set texture stage states
Texture[0] = <entSkin1>;
ColorArg1[0] = Texture; // stage 0 = skin texture
ColorOp[0] = Modulate2x;
ColorArg2[0] = Diffuse; // modulate by lighting
}
}
"; // end of the effect string
}
starter mat_bump_init {
// initialize the material properties
vec_set(mat_bump.ambient_blue,mat_model.ambient_blue);
vec_set(mat_bump.diffuse_blue,mat_model.diffuse_blue);
vec_set(mat_bump.specular_blue,mat_model.specular_blue);
mat_bump.power = mat_model.power;
// create the normals map for DOT3 bumpmapping
bmap_to_normals(mat_bump.skin2,2);
// set a lighting vector for DOT3 bumpmapping
mat_bump.skill1 = pixel_for_vec(vector(200,200,200),100,8888);
}
Personally, Oliver's effect is a little nice (I think). It more so compares to a good fallback for Normal Mapping. But Conitec's is more compatable, and it has no default lighting.
Btw, is that on level geometry? Could you post the script you used for it if it is? Thanks!
ewwww....
