Changing a material effects both text objects I am making a Banner for a friend, I have it mirrored and pretty, Same text twice, The main one with bevels and Glass. The one behind it as an Emission source for light to get a nice reflection.

Now here is the problem, I was wondering why it wasn't detailed, When I move back and fourth between the two Text items, They keep moving the properties! Example, I change the color of the Emission text, Suddenly the Glass text isn't glass but it also has Emission property now, For some reason when I change anything on one, It changes in the other.
Most likely this is because both text objects are assigned the same material (this could happen if you duplicated one from the other).  If a material (or any other datablock, i.e. particle system, image, etc.) has multiple users it will display the number of users in a small box to the right of the material name.  To make a single user copy of the material simply click on that box.


The material "Material" has 2 users, clicking on the 2 box will create a new material with all the same properties and name it "Material.000".  Changing this new material will not affect the original material "Material".
