How to build lighting for large outdoor scenes

My outdoor scene was very large, if i use dynamic lightingsThe scene will be very carleton.Are there any better lighting schemes?

If your map is very large and you have many objects (like foliage) then building lighting isn’t likely to work for you–it can easily use up too much RAM to do that and if you can get it to work it will use a lot of storage space for the lightmaps so for large scenes it’s better to use dynamic lighting. For outdoors it’s easier to use something like a directional light and skylight, you can also look into heightfield GI for landscapes and LPV GI
