The Toon Point light is designed to work just with Toon materials. This adds a Point light to the scene, much like the native Point light in Maya®. Position is important, and rotation does not have any effect on the illumination, as this light source type illuminates in all directions. The Size In Viewport and Power attributes have no effect on the light source due to the stylistic nature of toon shading. The Texture attribute controls the light source's overall brightness. You can control this with the slider value, or by using a Texture map.
