Need help editing map LODs

[D-Tech Gaming]

Hello everyone !
I am the author of Project REVIVE a GTA 5 graphics mod.
for the next update of my mod I'd like to add-in and improve upon the reflections in the buildings' glass panels.
I tried editing timecycle values like "light_ambient_bounce_enabled" and "light_ambient_bake_ramp", and other "reflection_" related values.... but they create a weird bug.

The building windows act as a SCREEN of some sort and reflect whatever is directly behind the player. Its like watching the rear parking cam of the vehicle on the building windows.

So, I heard another way to edit those reflections is via map LODs... but i don't know how to do it. Can anyone help ?
