This looks interesting, but unfortunately the link in the thread is dead at the moment. Is there another place you know of where this mod can be downloaded?

Link doesn't work indeed but here's how to create the mod "manually"

Copy this text

[ClassInfo]
ClassName TMaterial
[LightParams]
Ambient 0.2
Diffuse 3.0

paste it into wordpad and save somewhere as LandLight.mat
Locate the folder where the map mods are let's say maybe il2root/mods/mapmods/maps/ and inside that there should be the folder -tex (or _Tex). Put Landlight.mat inside _Tex. Then play with the parameter
Ambient and Diffuse and see how the map lighting changes. The default game parameters are

Ambient 1
Diffuse 1

See what happens with big changes like

Ambient 0.1
Diffuse 30.0
etc

You don't need to exit game each time you change the parameter. Let's say you focus on a certain map, say Crimea. Open the map in FMB save mission with camera play and see how it looks. Then exit play and load some other map say online1. Exit FMB. ctrl+esc to desktop. Change parameters and save. Back to game load yuor crimea mission play it exit..online1 exit desktop change parameters .....The exit and going to other map is in order that the game forgets about the settings he has already for Crimea (it's a feature which speeds up loading of a map)
