2. Click on the ArcGISMapActor in the Outliner panel.
3. Set your API key under the Authentication section in the Details panel.
4. Click Play and select a city from the list.

How to Setup (Sample Viewer)

1. Click Play in Unreal Editor.
2. Input your API key under the API Key Drop-down.
3. Click the Sample Drop-Down and select Weather Query.

How it works

1. Create a new C++ class and make a http request to query a feature layer.
2. Create a new Blueprint Actor class
   • Create the event to place the data returned from the Weather Query.
   • Create a function to spawn the weather actor according to the data received in the query.
   • Attach the ArcGIS Location Component to the weather actor blueprint class.
   • Add aditional functionality to spawn/show different Niagra Particle Effects based on the current weather data returned from the Weather Query.
3. Create a widget for the viewport so users can select a city from the list fed from the feature service.

Note: You can use UE_LOG to print log messages in the Output Log window and see if you are gathering the data properly from the feature service.
