6.1 Scene» Shape: Defines the shape of an area light.» Attenuation Mode: Sets the falloff of the light intensity. ”Realistic Attenuation” issimulated by computing the view factor between the illuminated surface and thelight source, ”Custom Attenuation” uses the ”Light Attenuation” mode from the”Properties” frame.» Primary Visibility: Enables/disables the primary visibility of the light source in therendering.» Visible in Reflections: Enables/disables the visibility of the light source in reflections.» Interactive Quality: Sets the quality for Interactive rendering. Selecting a highervalue results in a higher number of shadow rays for this light source and thus ina higher quality and a lower rendering performance.» Still Frame Quality: Sets the quality for Still Frame rendering.» Light Profile IES light profiles are standardized light emission data sets with correctphysical light attributes. Those profiles simulate correct light falloff and intensities.» Use Light profile: Activates/deactivates the use of light profile.» IES Profile: Specifies the path to a IES profile.» Set Profile Shape: Automatically sets the shape of the light geometry to the definedshape within the IES profile.» Visualisation» Show All Lights: Unhides all available light source geometries in the scene forvisual feedback and interactive transformation actions like scaling, rotation andtranslation.» Hide All Lights: Hides all available light source geometries in the scene.» Show Light: Unhides selected light source geometry in the scene.» Hide Light: Hides selected light source geometry in the scene.99
