HOW TO INSTALL ESTERLON;
This is a standalone map; it doesn't work with any other map mod or the base game. Please follow the installation instructions below to use this map.
USE ONLY the files above in the download link. (No other mega resources version than the above, not Reforma.) The use of other mods is at your own risk. I strongly recommend using only these two mods to help us test the map as normal.
Install. Place zReforma_esterlon_v1_6_10_157.scs into your mod folder, located at your documents/American Truck Simulator/mod, also do the same for the other file and place Reforma_MegaResources_v2_9_5_2_157.scs scs file into the same mod folder.
*Open up the game, in the main menu, directly hit the Manage Profile button
*In your profile management, hit the button, "New Profile", it's important to create a new profile, rather than using an existing one to be able the mod to work properly.
*Do some basic configuration to your new profile, such as the character's name, picture, truck design, company image, and company name. It's preferred to select your local language (or English), not "united states as default" even if you are from the US, the map works in a metric system, so you can be able to match the truck speed limit with the signs. When you have done lastly, hit the Mod Manager icon at the top left.
*It's important to keep the LOAD ORDER in the mod manager as follows;
-Reforma Esterlon v.1.6.10.157
-Mega Resources 2.9.5.2.157

This will allow the mod of Esterlon to read some specific assets that override some of Mega Resources assets. DO NOT use Esterlon in your normal profile or the base game (or along with the Reforma map, because this mod makes several changes over the map base which some stuff will be seen differently and might not be wanted.
*Lastly, at map module, select Esterlon.mbd and hit create button;
*Next you will have to set your controller setup and select your first location, which you can pick from these 5 cities;
