I want to tell you about the Grid Projector, a handy tool that is used to visualize a scale in any Unity scene. It's one of the Standard Assets in the Effects package. So, you may need to import it into your project. To import, perform the following steps:
- Select Assets in the main menu bar and then navigate to Import Package | Effects.
- The Import dialog box pops up, containing a list of all the things that can get imported. Then select Import.
