Luckily for you, this guide is here to help you out. With the usage of some techno-wizardry, you'll be off to the races in no time!

But before we begin, we must go over what is required to actually pull this feat off.
You'll need:

• Jabroni Brawl: Episode 3 and it's Authoring Tools[http//steam]
  
• Counter-Strike: Global Offensive and it's SDK[http//steam]
  
• MIGI (Multi Item_Game Includer)[zoolsmith.github.io]
  
• Hammer++ (CS:GO version)[github.com]
  
• Knowledge of how to use batch files
  
• Patience

With that all out of the way, let's begin.

Following the instructions for installing MIGI on its website, you'd know to run the MIGI executable inside of CS:GO's root directory ("...\steamapps\common\Counter-Strike Global Offensive"), doing so will create a folder titled "migi", this is what MIGI uses to run CS:GO with installed addons and we plan to do the same thing to essentially trick Hammer++ into working.

If you've already run the MIGI executable and that created the folder, rename it, afterward run MIGI again, it'll create a new "migi" folder, rename this new folder to whatever you want, for simplicity, we'll rename it "jbgo", after that you can rename the original "migi" folder back in the event you ever want to use it for CS:GO.

Inside our new "jbgo" folder, there will be a folder named "csgo", open it and you'll be greeted with this:

(ignore that scribbled out folder, we're creating that right now)

Inside this directory create a new folder, call it whatever you want, but again, for simplicity, we'll call it "jbgo" again.


Go inside this newly created folder, now this is where things get interesting!
Download this text file[cdn.discordapp.com] and drag it into your new folder, open it because you may need to make some modifications.


All you want to do is change the "JBPathSE" and "JBPath" to point to your own Jabroni Brawl "sourceengine" and game directory respectively, after that save it, rename the extension from ".txt" to ".bat" and run it as administrator and watch it get to work.


If you've done it correctly, you should see all these folders created in your "jbgo" folder, what we've done is create symbolic links between Jabroni Brawl's VPKs and our "jbgo" folder, don't worry, symbolic links are just that, links, they won't affect your storage space.

We're nearly there!

Now, what you want to do is go back a folder to your "csgo" directory inside of your "jbgo" MIGI folder.

(In case you got lost just there.)

Download this "gameinfo.txt" file[hastebin.com] and drag it into this directory, overwriting the one currently in there, now you may have to make modifications to this text file to so open it up.


What you want to do is first two Jabroni Brawl directories listed there to point to your "jbep3/custom" folder and just your "jbep3" folder, this will load any mods and/or any loose files you have in your Jabroni Brawl installation.

For the "main content VPKs", you just want to rename the folder titled "jbgo" with whatever you named your folder inside the folder you're currently at, for example, mine is just "csgo/jbgo" so every entry there would be:

You're in the home stretch now champ!

Head into your "Counter-Strike Global Offensive/bin" folder and open Hammer++, go to the top and select: Tools -> Options and create a new configuration with the "Edit" button.


After that copy what I have here with the rest of the options, look at these closely however, you may need to translate some of them to your own directories depending on if you named certain folders differently than what's in this guide.


For build programs, just point them to the launcher and compile tools include with Jabroni Brawl's authoring tools, after that, click OK and restart Hammer++.


After that, re-open Hammer++ and you're done! You can now start creating JB3 maps while utilizing all of the improvements that come with using Hammer++.

Now, I haven't actually gone in-depth with this, testing wise, but I can guarantee that you can create and compile a map just fine with this method, although I have noticed at least two oddities with this approach, one minor and one very major:

• CS:GO assets may still be listed in areas such as the Texture and Model browsers despite JBEP3 not actually having them. (Most likely something to do with MIGI including some base CS:GO assets for it to function on its own) Just know that these assets won't work in Jabroni Brawl (at least for now).
  
• STAY AWAY FROM THE MODEL BROWSER, right now, Hammer++ for CS:GO does not support MDL versions that differ from CS:GO's own, meaning that attempting to use the model browser to look for any non-CS:GO based asset will crash Hammer++ upon attempting to load, until Ficool2 adds support for multiple MDL versions, stay away from the model browser, if you must, create the block-out of the map in Hammer++ and use JB3's own Hammer for the rest.

But aside from that, there's nothing else, I wish you good luck in your Jabroni Brawl mapping carrer, and make sure to check out other Jabroni Brawl steam guides and the VDC page for more mapping/modding information.
