To reduce the latency of lighting updates in a large world, Enlighten can automatically reduce the lighting resolution when the viewer is far away. When lighting LOD is enabled, distant areas use a lower lighting resolution.
To reduce the latency of lighting updates in nearby areas, Enlighten normally updates distant areas at a reduced rate. , distant areas can instead be updated at the full rate.
In World Settings, under Enlighten, the following parameters are used for lighting LOD.
To set the distance from the camera at which Enlighten switches to a reduced resolution of probes, use the Probe LOD Distance property. When the distance is
0, Enlighten uses the highest resolution probes for all meshes.
To enable lighting LOD for a landscape actor:
- Select the Landscape actor and check Enable Landscape .
- Run the Enlighten precompute.
By default, Enlighten automatically chooses the number of detail levels. You can also specify a minimum number of detail levels: in World Settings, under Enlighten, set the Minimum Landscape LOD Count before running the precompute.
To set the distance from the camera at which Enlighten switches to a reduced resolution for the landscape lightmap, use the Landscape LOD Distance property. When the distance is
