shader: color white after a precise z-value
hi,
i'm new to unity and it's difficult to understand shaders :p . what i want to do is to color a mesh after a precise z-value with 0.5 alpha white. it seems like a fog but at a precise point, independant from the camera.
i tried with some z-buffer things and depth but it didn't succeed (z-buffer is more for the camera but i want really uniformely color after the z position 0.5);
can someone tell me how. it will spare me 2-3 days ;)
thank you!

ok, i did just what i want: void surf (Input IN, inout SurfaceOutput o) {
if(IN.worldPos.z>0.5) {
o.Albedo=tex2D (_MainTex, IN.uv_MainTex).rgb*2; //after 0.5 : 50% white.
} else{
o.Albedo = tex2D (_MainTex, IN.uv_MainTex).rgb; // in front : normal
}
}
