## Included Assets

#### BP_DefaultGameMode

Base game mode, used to configure custom blueprint classes. Use as example for your custom game mode.

#### BP_DefaultGameState

Store the current time, and serve it for all clients playing on server.

#### BP_DefaultPlayerController

Store the user specific clock type preference, and draw the widgets on player viewport.

#### BP_WeatherManager

This is where the magic happens. When placed in the level you can configure the custom settings and set a reference for the world directional light, also BP_DefaultGameState must be set in your game mode. (**This is extremely important, if this is not done the system will not work properly**).

Some of the custom settings:
