Texture not visible

Can you post your patch with the texture that you want to add ? dont forget to add the .fx to the zip

deleted.

this shader does not use the texture input, but you can change that by adding on line of code in the pixelshader:

float4 col =  cAmb;
col.a=cAmb.a;
if (maxdepth != 0.) {
col.rgb=lerp(cFog.rgb,col.rgb,In.depth);
}

float4 texCol = tex2D(Samp, In.TexCd);

return col*texCol;

thank you very very much, it works :)
