Rx3 File Editor

Open the PNG in Photoshop (with Intel DDS plugin) or GIMP (free).

Click File -> Save. Then, use a "Regenerator" (or Frosty Mod Manager) to clear the game’s cache. Launch the game. Your gold kit is ready.

To understand the editor, you must first understand the file. An RX3 file is a proprietary archive format used by EA Sports in their FIFA series (and other titles like Fight Night). Think of it as a container, similar to a .zip or .rar file, but specifically structured for the game’s engine (the Ignite engine and its predecessors).

These containers hold the assets that make the game look and sound the way it does. A single RX3 file might contain:

Because the game natively reads these compressed archives, modders must unpack them, edit the contents, and repack them. This is where the RX3 Editor comes in. rx3 file editor

As EA Sports transitions fully to Frostbite Engine 4.0 and beyond (currently FIFA/FIFA FC), the older RX3 tools are struggling to keep up. EA has started embedding shader binaries directly into the RX3 containers, making it difficult for tools like FIFA Editor Tool to parse the data.

However, the community is resilient. The new wave of modding focuses on FIFA Legacy (FIFA 16) for career mode depth and FIFA 24/25 mods using Frosty Editor. For the foreseeable future, the .rx3 format remains the standard, and learning an RX3 File Editor is the single most valuable skill for a sports game modder.

The RX3 File Editor is more than just a utility—it is the gateway to game personalization. Whether you want to resurrect a forgotten league, create a dream kit for your favorite club, or simply fix the outdated boots on your star player, the RX3 Editor puts that power in your hands.

Start small: Extract a ball texture, change its color from white to gold, re-import it, and test it in a kick-off match. Once you see that custom asset in-game, you’ll understand why tens of thousands of players rely on this tool. Open the PNG in Photoshop (with Intel DDS

Final Pro Tip: Always keep a clean backup of your data folder. A single wrong click in RX3 Master can corrupt a file, but with backups, the only limit is your creativity.

Step 1: Download and Install Download RX3 Master from trusted modding forums like FIFA Infinity or Soccergaming. Since it is a standalone executable (no installer), simply extract the ZIP to a folder like C:\Modding\RX3Master.

Step 2: Open an RX3 File Launch the editor. Go to File > Open and navigate to your game’s data folder. For example:

Step 3: Examine the Contents On the left panel, you will see a tree view. A typical kit RX3 might contain: To understand the editor, you must first understand the file

Step 4: Export a Texture Right-click on a texture and select Export. Save it as a PNG (easiest to edit) or DDS (preserves mipmaps). Edit the file in Photoshop (with NVIDIA DDS plugin) or GIMP.

Step 5: Import Your Edited Texture Click Import, select your modified image. The RX3 Editor will automatically recompress the texture into the game’s native format (usually DXT5 or DXT1).

Step 6: Save Your Changes Use File > Save (or Save As) to overwrite the original RX3. Always back up the original file first—a corrupted RX3 will crash the game on load.

You need the Team ID. For Man United, it is 11. The away kit is usually kit_11_1.rx3 (where 1 = away; 0 = home; 2 = third).
