The directional light, which is placed for you when you create a scene, is necessary to adjust the light intensity on 3D models, and the asset that produces this light is called the “light source” in STYLY.

In order to adjust the lighting, first select the “Directional Light” in the scene. Next, press the E key to display the rotation gizmo and rotate the light source to change the angle at which light shines on the 3D objects in the scene.
