Duplicate without copying materials?

Hello, I am trying to duplicate an object (alt+d and shift+d.) However, when i duplicate i want to be able to change the textures on the copy without effecting the original. Neither alt or shift d prevent double texture changes. How can i do this? thanks

you can link the material to the object instead of to the data… see dropdown next to mat name

Tanks a lot! i tried everything but the most simple thing… :stuck_out_tongue:

And if a material is linked to another object, just click on the number next to the material name to make it a single user
