I want to edit Altis, how to?

[Buck]

I have a MP mission where I added a bunch of placable items like trees and buildings, essentially created a town in part of the map that didn't exist before.

I essentially want to take this slice of altis that I have build and turn it into it's own usable terrain.

Is there a walkthrough or something that somebody can point me to that will let me open altis and edit that section of the map and remove everything around it?

I have zero experience with the terrain editor so any detail you can provide would be helpful thanks!

You can't man, you would need the map source.

I (and some other hundrets) want it too, but you need the permit and the source files.

You cant do it. You only can edit a missions

[Kiri Otoru]

well, actually, you can. by unpacking the map's .pbos and using them as a source in terrain bulder and Bulldozer. but I do not recommend it, especially if you have 0 exp with terrain buld for Arma. It is horrendous and very time consuming stuff.

How can you?When you unpack a .pbo you get the Data folder and other textures. The source folder doesn't show up,you would have to redo the highmap, sat and mask.

there is seven pbos only for Altis. also there is one common pbo for all vanilla maps.

Its still NOT allowed !

yeah, copyright and all that

you cant modify the elevation at all, but there are scripts that you can place into actors to remove the closest building/object, and then you can put your own buildings there. Would be a mission file, not a complete map edit. Not sure if the scripts work for removing rocks/trees, google is your friend.

there are mods in the workshop that add buildings both modded and vanilla into the in-game editor. You can just open the map in the eden editor and click/place the buildings
