I have issues to put a logo on a surface that already has a material and it make a pink color that blend with the transparency but on the right on the preview we can see the résulte that i want. It's only for one face of the 6 so i duplicate the material for one face and and the image on the new material, add the image on the uv editor and unwarp the face.

imho strange material setup... which UV should be used by texture coordinate node? and why non-color data for the image texture? is it a normal map? I can't understand what you wish to obtain, and which image are you using... – m.ardito Oct 18 '17 at 20:05

oh sorry the non-color data and the coordinate were a test i just forgot to undo that. – Baptiste Oct 18 '17 at 20:12

and i just begin with nods so if the material is strange you can say what's seems wrong – Baptiste Oct 18 '17 at 20:17

And @Baptiste, your setup looks good to me, except I would plug the Alpha into the Fac of the last Mix node. – SilverWolf Oct 18 '17 at 20:54

I tried and the preview looks better but it's steel look pink in the render. I don't understand what's wrong cause the preview is exactly what I want in my render. And my image is just a logo with no background. – Baptiste Oct 18 '17 at 21:01

Have you UV unwrapped it yet? – HappyBlenderUser Oct 18 '17 at 21:34

Probably you have some problem with your environment map not found or something like that that causes the material to reflect pink... – HenrikD Oct 19 '17 at 08:45

i change in the image texture node the extantion to clip and now i can see taht the pink is the rectangle of the image in the uv editor. – Baptiste Oct 19 '17 at 19:35
