duplicating objects

i duplicated an object and i assigned a new material to the new object but the previos object go the new material too!

how can i remove the link between them?

thanks in advance

If they are linked objects select one and press U in object mode.
If they are just duplicates with the same material, select one and delete the material from it and add another one or press the number to the right of the material name to make it a single user.

thanks for the quick reply. being a new user and not knowing simple things can be rather frustrating

thanks for understanding :slight_smile:
