Installation

Package Manager

  1. Open your Unity Project
  2. Open the Package Manager
    Package Manager Open
  3. In the Package Manager select My Assets
  4. Select the Fluid Frenzy package.
  5. Click the Download button in the top right.
    Package Manager Download
  6. After the download has finished click the Import #VERSION to project button.
  7. This will open the Import Unity Package window. Click Import.
  8. The core package should now be imported. The samples are not automatically imported to reduce the package bloating your project. If you want to import the sample scenes please follow the steps here.

Unity Package File

If you have previously downloaded the package you can add the project by importing the Fluid Frenzy.unitypackage manually.

  1. Add the package through Assets > Import Package > Custom Package.
  2. Select the .unitypackage file for Fluid Frenzy. The previously downloaded package is generally stored in:
    • windows: C:\Users\USERNAME\AppData\Roaming\Unity\Asset Store-5.x\Frenzy Byte\Shaders where USERNAME windows account user name.
    • macos: ~/Library/Unity/Asset Store-5.x/Frenzy Byte/Shaders
    • linux: ~/.local/share/unity3d/Asset Store-5.x/Frenzy Byte/Shaders
  3. This will add the package to the Package Manager.
  4. The core package should now be imported. If you want to import the sample scenes please follow the steps here.
