add the following to your Main script:

bmap envmap = <desertsm+6.tga>; //your environment map definition

// next: your material, the name has to be exactly the one of the wad texture you use, i chose "brushed_metal02"
material brushed_metal02
{
	skin1=envmap; //your environment map
}

starter load_shaders() // your starter that loads the shader at engine startup
{
d3d_automaterial=1;
effect_load (brushed_metal02, "envmap.fx");
wait(1);
bmap_to_cubemap(bmap_to_mipmap(brushed_metal02.skin1)); // mips for making it run faster
mat_set(brushed_metal02.matrix,matViewInv); // the important part for level geometry
        brushed_metal02.matrix41=0;
        brushed_metal02.matrix42=0;
        brushed_metal02.matrix43=0;
}
