I am currently working on a map with a specific intent in mind.
The nature of this specific intent requires that I remove all air based units from my map.

This is all well and good, and something I know how to do,
The problem I'm having is with the Tech tree, and editing its pre-req's.

Before all of you start screaming Firegraft or Memgraft or Stargraft or whatevergraft.
I have tried them, and I can't find one that will work with the most current version of starcraft [being 1.16.1]

The second half of my question comes from many many years of not using StarEdit.
If I remove air units from the game, and edit the tech tree, does this automatically require a map to be a UMS? or can it be melee or tvb or whatever I deem?


Any help and suggestions you all can offer would be awesome.

Well all you can do is disable each players ability to make air units, however without modding you won't be able to customize the tech tree itself. Editing which units can be built will require players to play in UMS else the map won't have your disabled settings.

Editing the tech tree requires modding. I'm not entirely sure how to do it, as I'm not a modder.
UMS is a requirement on all games if you want it to have custom triggers and units. All the other settings have a default set of triggers and units. I suppose modding can change that, though.

As for working versions of modding tools:

What, exactly do you need the tech tree changed for?

You can't play mods over battle.net in the same way you can play maps over bnet. Everyone has to load the mid before opening Starcraft.

Here.
FireGraft for 1.16.1. No EXE Edits, but oh well.
