 Actif3D supports the following light types.
-Spot light - The spotlight beam is restricted by a cone with an adjustable angle. Commonly used for downlights, lamps with lampshades, and sconces.

 ➕ Sun - Adds sunlight. An instance of the light is placed at the zenith point of the sky.
-> Lights can also be imported from a 3D modeling program. This method is usually more convenient than adding lights in the Actif3D editor, because it allows light sources to be attached to 3D objects, such as light fixtures.

 Lights have the following properties:
-Strength - The light strength
+**Strength** - The light strength
-Angle -  For Spot lights only: the light beam angle
-IES profile - For spot and point lights only: an optional light profile containing photometric data in IES format. Can be imported from a file with the 🖺 button
+**Angle** -  For Spot lights only: the light beam angle
-Size or Width & Height - The light size in meters. Larger lights cast softer shadows, smaller lights cast harder shadows. Depending on the lightmap resolution, excessively hard shadows can result in a pixelated lightmap
-Color - The light color
