Importing models from Roblox studio is a bit complicated than most give it credit for.
This is mostly a guide for those wanting to learn how to import Roblox Studio models into Battle RC, any other details are available in Okamifan1’s guide which I will link down below.

Remember to watch these, it will be essential.
When you are done watching the videos. Let’s get started!

There are 2 different ways to make robots

• [Using Roblox Studio]
  
• [Using F3X in a Roblox Game]

There is no preferred method obviously but they have their own advantages and disadvantages which I will go over.

ROBLOX STUDIO
Roblox Studio offers an option to use Unions, which helps to group parts.
Unions are really helpful to make textures because of what it provides.
This may seem not much but it will solve a massive headache when importing the model to Battle RC. That includes having to group up parts individually in Battle RC.

F3X ROBLOX GAMES
F3X Roblox Games offers different plugins to help with your build.
Also because you have a player model to move around oppose to a camera in Roblox Studio. It is way easier to position yourself as you build.
However this doesn’t provide u an option to group parts up, although u can with shift + G. It won’t translate over to Battle RC. Which causes a massive amount of parts that u are forced to organise in Battle RC without going to Roblox Studio and union them together.

I will not go over how to build robots in either games because this is mostly a guide for importing bots from Roblox Studio to Battle RC BUT.
MAKE SURE they have:

• [Wheels]
  
• [Chassis]

You are NOT required to change the colours of the parts into individual ones, that is not necessary for Roblox imports.

This step is important to cut the amount of time needed to import bots to Battle RC.

Mainly Union is used to group or cut parts.
ByteBlox talked extensively about Unions and I recommend you checking their video about Unions:

However we will mainly use the Union tool in the Union section to group parts together.
We can’t group parts normally because Battle RC will not register them as a grouped part unless you use Unions.

Remember to make sure you don’t put 2 different colored parts into one Union, because Battle RC will treat them as one colored part instead of 2 separate colored parts.
















Each individual wheel should not be grouped together or the bot will struggle to move left or right.
this entire procedure is optional but it is recommended for less lag and suffering on the importing part of this guide.

This will be the hardest part of importing your robot to Battle RC.

First you need to do is sizing your bot to around the size of a 250x250 Square [500x500 for bots like HUGE or Mammoth]
This makes sure your bot won’t be too small when you import them into Battle RC.

Importing from a Roblox Game to Roblox Studio (OPTIONAL)
This guide is NOT required if you already made your bot in Roblox Studio.
Install the F3X import plugin from the Toolbox. You can easily find it by searching F3X in the plugin search tab.
Click the Export button (Shift + P) to receive a 4 digit code.
Click on the import plugin and type in that 4 digit code to import your bot into Roblox Studio!

Positioning:
The bot needs to be pointing downwards, top facing the z axis. If it is facing in any other direction. they will be facing the wrong direction when ported to Battle RC.
Make sure the bot is at the centre of the map.
You can find where the centre is by opening a new place and shrinking the baseplate with the F3X plugin. You can find it in the same search tab as the import plugin.


Make sure:
no spinning blades are touching the ground.
the wheels are touching the ground.
If you failed to detect these errors, u need to reposition them and start all over again.

If you done it correctly, it should look something like this.











After that, right click on the ‘parent’ of the model. You will find an option to “Export Selection”.
Then you can export the .obj file of your bot onto your computer.
It is the same as importing from Tinkercad for now.
You need to open Battle RC, go to workshop and select new bot from the drop-down menu and import the .obj file of your bot.

You can see Okamifan1’s guide in case you have no idea how to organise the bot’s parts.

There are some minor fixable errors that comes with importing bots to Battle RC.
Discolouration, mostly common for yellow which often turns into orange during import. It can be easily fixed by changing the color yourself ingame.
Missing Decals, these are mainly cosmetic errors because the game doesn’t recognise Decals or SurfaceGUIs,

With all of those tips and tricks.
You are ready to create your own bot from Roblox Studio!
