Hello to the one who's reading this! As we all know, cities xxl divided the environment pollution into two categories - air and car. I see this poses a problem to the old plaza mods like Wooded Forest Area or Total greenery mod from cities xl. They look good in cities xxl but they don't affect air or car pollution. When you click on them in the game, they show the old pollution level from cities xl. I've taken a look in Wooded Forest Area classes and added <SelectionLayer>Array_PollutionAir</SelectionLayer> in the <Display> section and when clicking on the plaza it shows the air pollution correctly but it doesn't affect it. My question is how can I modify the classes(or other files) to reduce air/car pollution? I've added <LayerName>AntiPollutionAir</LayerName> in <Shape02> and/or <Shape01> but to no avail.
