 Since v0.8.4.2314 lighting and iso surface detection is also supported.
-Iso surface detection tries to evaluate a surface during raytracing.
+To activate lighting for a volumetric mesh, please use:
+<file pascal>
+GorillaVolumetricMesh1.UseLighting := true;
+</file>
+After it was activated, the implemented functions try to detect a surface from the given 3D data.
+This is called IsoSurface detection.
 Because this method always depends on the data, you can control this detection by **IsoSurfaceLimit** property.

 __Notice:__ For PBR (physically based rendering) it does not need any PBR texture, instead it will use the //AOBias//, //RoughnessBias// and //MetallicBias// properties.
