Shadow:Intensity: Changes the intensity of casted Shadows.Shadow Quality:Sets the shadow quality for interactive visual feedback and for final renderquality.This parameter works only in raytracing mode.Important: Setting this parameter to high values, increases calculationtime.Shadow Map Resolution:Sets the quality for OpenGL shadow maps. Higher values increase the quality.Position/Direction:Use Camera: Sets the Light position and direction to the current cameraposition snd direction.Create: Creates a new light source. Three different types are available:- Directional Light- Spot Light- Point LightDelete: deletes the selected light sourceRename: The user have the possibility to rename light sources.Change Type: Converts existing light sources to different light source types.Light specific parameters:Spotlight:Cone Angle: It is the angle, in degrees, from one edge of the light's beam to theopposite edge.Penumbra Angle: The Penumbra Angle controls the falloff, in degrees, of theedges of the beam. This can be a positive or negative value.If it's positive, the falloff will occur from the edge of the light determined by thecone angle, outward by the penumbra angle. Therefore, if the Cone Angle is setto 30° and the Penumbra Angle is set to 5°, the light has a total angle of 40° (30+ 5 + 5 - that is 5 degrees on each side). The beams falloff would begin at 30degrees and would fall off to an intensity of 0 at 40 degrees.Light Attenuation: Sets the Falloff of the light intensity.Three values are available:- Off (Light intensity of light is constant in relation to the distanceof light)- Linear (Light intensity decreases linear in relation to thedistance of light)- Quadratic (Light intensity decreases quadratic in relation to thedistance of light)Area Light:Use realistic Falloff: Sets the Falloff behavior of an area light to quadratic.Size: Sets the area light size in mm. The Bigger the light, the brighter. Sets theshape to a rectangular area light.Pointlight:Light Attenuation: Sets the Falloff of the light intensity.Three values are available:
