I don't know, I tried it myself, but it didn't work. Maybe you could take a look at how the developers did it on the corresponding map?

It also doesn't work. It says, value was nil when getting global with name "round"

You have version 3.0 of the game, and this function doesn't work in that version. Also, the array seems suspicious; I think there's a mod in the map that adds some types of lighting.

My game version is indeed 3.0. And is there really no way to make SetAmbientLight work?

SetAmbientLight should work on any version. Theoretically, at least. But the round function won't.

local SET_LIGHT_GROUND = { 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa', 'Su' }
if mod(GetDate(DAY), 3) == 0 then
local lightIndex = mod(round(GetDate(DAY)/3),7)+1
SetAmbientLight( GROUND, SET_LIGHT_GROUND[lightIndex], nil, 0 )
end

doesn't work either. It says, value was nil when getting global with name "round"
attempt to call a nil value

The map uses its own files;)
'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa', 'Su'
Copy these files to the root of the map and check at least "Tuesday" ;) (and there will be no xdb#xpointer(/AmbientLight) there). You can also easily extract the lighting you want from the resources and put it into the map.
"round" is rounding, you probably won't need it, so don't use it (or better, set it to 3.1 ;) )

Oligarch, here's what I found in one of the original missions (3.1):

function SetLight( level, time )
	SetAmbientLight( GROUND, "fog_light_level"..level, true, time);
end;

The call is quite simple in one of the functions:

function IsOrnellaMeetArantir()
    SetLight(2, 3);
end;

startThread(IsOrnellaMeetArantir);

The script location: Maps/scenario/A2C1M4
Maybe this will help ;)

startThread(IsOrnellaMeetArantir); in this case, the function starts when the game begins; instead, you can use a trigger and call the same function, for example:

Trigger(REGION_ENTER_WITHOUT_STOP_TRIGGER, 'youRegion', 'IsOrnellaMeetArantir');
