UMB Colombia

The map [UMB] Colombia is based on real satellite data of northern Colombia combined with a free interpretation of a Colombian coastline. It was/is being developed with a strong focus on tactical mil-sim, but should work with most other game modes, too.

Big shout out to the guys at 77th JSOC, who have helped and continue helping with placing down objects and testing the map.

You can expect updates on a regular basis, as we are pushing forward to get this map finished.

Numerical values are too small for some grass, so the AI can see much better through grass

No worries, I get the workload must be never ending! Love the terrain mate!

Well maybe one day... every update breaks the map for the Alive Index, so I am not really gonna push an update for removing things I forgot about ;)

Quick preview of the map, love it so far - I noticed in the South East corner there is a collection of roads, logs, trees and rocks you've used, will that remain or be removed eventually? (I get weird with details like that, so I just need to know whether I should get over myself or not haha)

@Chaser - You're welcome! I know some people do not know as much as we might and to 'help them', stuff needs to be 'pointed out'. I suspect this is how you got your 'start'. I know it was for me and STILL IS! ;)

As you know, ARMA can be quite complex in things and on some games such as RDR2 or COD, weather IS part of the map, so I do understand their question.

Thanks again for your kind words as well as your map!
