How do I edit a specific area of an LOD on a building?

Ill like to know how could I edit a specific area of a buildings LODs and reduce the polygon without getting completely rid of another. My example and my situation Ive got a building and im working on the lods for such building but my issur is that the windows disappear when i reach an lod like 3 or 4 ill like to keep the windows and reduce the brick polygons of the building?

I’d say your best option is to tune the LOD process manually.

You can turn off auto compute LOD distance:

Then you get to choose how many LODs you have and at what distance they happen.
