As noted, you can unlink the material if you want to control the attributes of the material on each object independently.ĭimension follows a fairly subtle set of rules as to when it links materials and when it doesn’t. When you changed the material color, it was updated on both models. This created a single material instance that was linked between both models. In the preceding example, you sampled the material for the Jar Lid model from the Cup 2 model.
