To start using the plugin, there are two Prefabs that can be found in the Plugin's folder which will be all you need to stream your models inside Unity Engine. The Stream Controller, and the Streaming Model.
You can drag and drop both prefabs inside your Unity Scene and be ready to start streaming your converted 3D model inside the engine.
The Stream Controller should only be added once, and it controls the streaming feeds inside your scene, you only need to set the Main Camera in the Camera field. The Streaming Model is a prefab to be used with all models that will be streaming from the cloud into your project, you only need to add the URL of your converted model into the URL field.
Once that's set, press play and your streaming models will already start streaming inside your project!
