    Hi!
    I was wondering: is there a way to “highlight” or apply a color overlay to an object without having to tweak or affect its material.
    Or is it possible for several objects to share the same material, but to individually change one setting in this material (a color input for example?) for each object…?
    Thanks for the help!

    I update this post to see if I can get any help…
    The idea would be to “add” a color overlay on a given object without affecting it’s material… if this is even possible…?

    object.objectColor (in RGB format)

    Puzzles and JS coding. Fast and expensive.

    If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

    New update: problem solved!
    I managed to get what I needed (a single material, which looks different from one object to another in terms of color and transparency).
    For this I used the “Object Info” node in the Blender material definition (see here).
    The “Color” output controls the color of the overlay, and the “alpha” output controls the overall opacity of the material.
    Be careful if you use normal maps in your material to make sure that the normals are correctly computed (if they exist at all!) for the objects to which the material is affected. Otherwise you may experience unexpected render issues (see here to force the tangent computation on your geometry if this attribute does not exist)… I struggled to find this one!!
