LightMap Tools will be helpful for you if you use baked lights but you don’t have a render farm to build.
It allows you to build lights only for the selected level part you are working on.
By setting other actors Lightmap Resolution to 1 it drastically decreases build time.
This way you can quickly iterate and see the result without the need to rebake the entire level.
