I’m modeling this OP-1 synthesizer. See those empty circular buttons on my model (first image)? Those should each have a unique decal, as seen in the photo ref (second image). In my model, those buttons are linked instances of one object. What’s the best way to assign unique textures to each of those buttons, while keeping the object data linked? My ideas:
Set materials to be per object, instead of per data, using either the drop-down at the top of the Properties > Material panel, or in Blender’s preferences.
Use floating transparent textures, positioned right above each button, and turn off shadow casting for these floating decal objects. (I don’t like this method, since it might might cause Z-fighting or other problems later.)
But maybe someone here has a better idea for this particular case. Thanks!
