Change the limit of the troops (Company of Heroes 2)

The question still relevant? You can take any map, open it in WorldBuilder, Click Scenario-Scenario Properties, rename map name. (Then you can distinguish the map). In the folder with the map there is a file ИМЯ_КАРТЫ_ID.scar. Open it with Notepad and add the following:
--Population cap override value
g_popCapOverRide = 300

for i = 1, World_GetPlayerCount() do
local player = World_GetPlayerAt(i)
Player_SetPopCapOverride(player, g_popCapOverRide).

It will look like this:

OnInitID function()
--Population cap override value
g_popCapOverRide = 300

for i = 1, World_GetPlayerCount() do
local player = World_GetPlayerAt(i)
Player_SetPopCapOverride(player, g_popCapOverRide)
end

-- [[ Markers ]]

-- [[ Squad Groups ]]

-- [[ Entity Groups ]]

end

To save the file. In WorldBuilder click File-Export Package. Play.

Where can I find the default maps? How to open them with WorldBuilder, if he can only open the sgb and scenref&
