I have these two objects below. The one named -outerdark was a copy of the -innerdark.
I can move and resize these objects independently fine.
However, in the shader, if I change one’s color, the other’s color changed color too. Are these objects somehow linked in terms of the shader, and if so, how do I unlink ?
For any linked data try the Object menu, for a material try the number to the right of the name of the material… If you hover over it with the mouse you should get a tooltip.
