rendu pixar with color ramps

Hi all,

I asked me how to have this result (I’ve done it with matcap) but the lightings don’t rect with this model.

Maybe I could have this result with the color ramps, but I don’t know how to use the color ramps horizontaly and over all verticaly (you will note that the gradiant of picture colors are mostly degraded verticaly).

I’d like to have the same result but not with the mapcats,

Thanks for your help…
