This is the documentation for Enlighten.
Enlighten is the leading real time global illumination solution for game developers.
Enlighten computes diffuse indirect lighting using radiosity. Unlike other radiosity solutions, Enlighten lets you move and change lights and materials at runtime.
| Direct light only (not provided by Enlighten) | Indirect lighting only (provided by Enlighten lightmaps) | Combined direct and indirect lighting |
|---|---|---|
| UE4 computes direct lighting and shadows. | Enlighten computes the indirect lighting. Enlighten simulates multiple bounces of the bright sunlight to realistically illuminate the dark areas. | Direct and indirect lighting are combined in the final image. |
