 So there are two places to configure your scene for global illumination: viewport and light sources.
-==== Viewport ====
+==== TGorillaViewport ====
 The first and important step is to activate global illumination in the TGorillaViewport instance of your scene.

 |GlobalIllumSoftness|A separate render pass softens the raytracing result. Especially useful to soften shadows. The higher the value is, the more soften the rendering becomes. Values between 0.0 and 5.0 are allowed.|
 |ShadowStrength|Defines how intense/dark shadows will become. Default value is 0.4. Allowed values are between 0.0 and 10.0|

+==== TGorillaLight ====
+Because we also support light scattering in RTGI computation, it might be necessary to modify default settings.
+It is recommended to use the TGorillaLight component instead of a TLight component in your scene.
+__WARNING:__ The default FMX light component does not support configuration of light-scattering.
+To deactivate Light-Scattering for a specific light source, set ScatteringIntensity to a value less than 0.00000001.

+|ScatteringIntensity|Light scattering in global illumination rendering can be controlled for each light source separately. ScatteringIntensity defines how intense the light scattering will be mixed into the final image.|
+|ScatteringExposure|Light scattering ray exposure parameter|

+|ScatteringDensity|Light scattering ray density parameter.|
