If you don't care i may setup a arma commander battlefield on this map with the warhammer mods if it works smooth it depends if it works well with arma commander or not for my steam workshop for everyone to enjoy and on my youtube channel you get all the credit of course

I'd start with this tutorial and make a proof of concept map or two first before you make what you actually want to make.

It is a pretty big undertaking to learn though, just so you are aware. Also are some extremely nice and helpful people on the "terrain_makers" sub-channel on the Arma 3 discord if one can't solve a problem oneself.

Where can I go to learn how to make maps like this? I would be interested in learning just not sure where to start.
