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.
