It provides a graphical view of the relationships between assets and provides support for visually understanding dependencies.
For example, by checking the reference relationship between Material and Texture or Shader, or by checking the reference relationship between AnimatorController and AnimationClip graphically, you can immediately make decisions about project organization and asset modification, so productivity can be expected to improve.
It will also automatically start rebuilding dependencies when changes are made to the Project (you can also request a rebuild manually)
Dependency rebuilding is done in the background of the editor, so you can use it without compromising the usability of Unity Editor.
