Go here and you will probably understand the problems behind texture mapping to objects other than a sphere. Or, maybe you will see some way to achieve it for all of us!!!

Also, for your card you may need to use: <bmap_to_uv> instead of <bmap_to__normals>. And you *might* not be able to pull off the projected tex in <TextureTransformFlags[2] =count3 | projected;>.

Okay now i can map a cube but something is wropng with the texture...
see the script... the texture used is a simple texture:





//bmap bmp_envcube2 = <skycubesun+6.tga>; //cube image
bmap bmp_envcube2 = <water_shader.tga>; //a normal texture 2d

// generate a matrix that transforms camera space back to world space
function mtl_env_view()
{
mat_set(mtl.matrix,matViewInv);
// reset the translation part of the matrix
mtl.matrix41 = 0;
mtl.matrix42 = 0;
mtl.matrix43 = 0;
}

function mtl_env_init()
{
bmap_to_cubemap(mtl.skin1);

//bmap_to_uv(mtl.skin1);

mtl.event = mtl_env_view;
mtl.enable_view = on;
}

material mtl_envcube2 // environment cube
{
skin1 = bmp_envcube2;
event = mtl_env_init;
//skin1 = reptile; // set a reptile skin
effect=
"
texture mtlSkin1;
texture texSkin1;
matrix matMtl;
technique cubic_environment
{
pass p0
{
Texture[0]=<texSkin1>;
Texture[1]=<mtlSkin1>;

AddressU[1]=Clamp;
AddressV[1]=Clamp;
//TexCoordIndex[1]=CameraSpaceReflectionVector;
//TexCoordIndex[2]=cameraspaceposition | 1;


//TextureTransformFlags[1] =count3 | projected;
TextureTransformFlags[1]=Count3;
TextureTransform[1]=<matMtl>;


}
}

Paste the script , and apply it to the terrain model (came with 3dgs)
///

I guess you have to remove the "+6" from the filename of your cube image because that makes the engine think it was a cube!

lolll.. The +6thing is for test! you can see the that line is commented! Thx anyway. eheh

o_Oooops! Sorry man just overread that one

OKay I finish the shader script! finaly..
This shader use a environemnt cube, as skin1 mtl
and the rest is a terrain.. is just works well for plane surfaces...

Can be use for ice ground..or wet envirnoment (alpha selection)

{
//...maybe you should copy the mat_model properties here...

mtl.event=mtl_envplane;
