- 11. Taking Advantage of Unity Pro
- Index
It doesn't matter how organized you keep your project folders, there will be times when you will need to search for one or more specific assets. To make things easier, Unity 4 includes the Project browser. In this recipe, we will learn how to save time by using it.
All we need to follow this recipe is a collection of assets. We will use Unity's Terrain Assets to populate our Project view.
Let's take a look at the Project browser:
- Import the Terrain Assets package (Assets | Import Package | Terrain Assets).
- Browse through the Assets subfolders to see the files that have been imported and how they are organized, as shown in the following screenshot:
- Now let's search for all the assets containing the word "Palm" in their names. On the search field located above, type in
Palm. Observe how every file and folder is listed on the search results window. - Click on the Save Search button (the one with the star icon) and name your search as
Palm.
- We could filter our search results by tag or file type. Click the Search by Type button (the one with a circle, triangle, and square) and select only the Models and Textures categories. You can select multiple options by holding Ctrl (Windows) or Command (Mac).
- Click on the Save Search button and save it as a new filter (name it
Palm Models and Textures). - Browse through the other filters saved in Favorites—they are shortcuts to browse through specific file types (All Materials, All Models, and so on).
Unity's new browsing system scans through the assets and lets you save and organize your search results.
