Minecraft World Conversion Guide, For Bedrock and Minecraft with RTX

Why Convert Your Java World to Bedrock for RTX?

If you've invested countless hours building an epic Java world, you might be wondering how to experience it with stunning ray tracing and PBR textures in Minecraft with RTX. The good news is that world conversion is possible, but it requires a specific process to move from Java to Bedrock edition. In this guide, we'll walk you through the steps to convert your Java world to Windows 10 Bedrock, enabling you to enjoy it with the latest RTX enhancements. However, be aware that this process is not official and may not be perfect, so always back up your worlds before proceeding.

Prerequisites: Official and Unofficial Tools

Before diving into the conversion, you'll need to gather the necessary software. Ensure you have the latest versions of Minecraft Java and Windows 10 Bedrock editions installed. Additionally, you'll need Minecraft with RTX (available via the Xbox Insider Hub) if you plan to use ray tracing. For the conversion itself, you'll rely on third-party tools: MCC Tool Chest (Bedrock Edition), MCA Selector, Forge Installer, and WorldEdit for Forge. Make sure the Forge and WorldEdit versions match your Java edition version (e.g., Forge 1.15.2 for Minecraft Java 1.15.2). Also, update Java to the latest version to avoid compatibility issues.

Locating Your World Files

You'll need to access your world files for both Java and Bedrock. The default locations are:

• Java World Saves: %USERPROFILE%\AppData\Roaming\.minecraft\saves
• Bedrock World Saves (UWP): %USERPROFILE%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds

Familiarize yourself with these paths, as you'll be moving files between them.

Step 1: Update Your Java World

If your Java world is older than version 1.15.2, you must update it before conversion. Start by installing the latest Minecraft Java edition and Java runtime. Then, make a backup of your old world. Open the latest Java edition and load your world; when prompted, update it. Enter the game, then save and quit. This ensures your world is in a compatible format for the conversion tools. Skipping this step may cause errors during conversion.

Step 2: Extract Your Build with WorldEdit (If Needed)

For complex builds or if you want to transfer only specific parts, you can use WorldEdit to create a schematic. First, install Forge and WorldEdit for your Java version. Open your world and use WorldEdit commands to select your build and save it as a schematic. The schematic file will be stored in the .minecraft\worldedit\schematics folder. Then, create a new Java world, paste the schematic at your desired location, and save. This step is optional but useful for transferring builds to a fresh Bedrock world.

Step 3: Clean Up Unwanted Chunks with MCA Selector

MCA Selector helps you remove unnecessary chunks from your Java world, reducing conversion time and file size. Run mcaselector-1.9.3.jar (or newer) and open your world's region folder (e.g., %USERPROFILE%\AppData\Roaming\.minecraft\saves\WorldName\region). The world map will load. Use the mouse to navigate and zoom. Select chunks you want to delete (e.g., unexplored areas) by left-clicking and dragging; right-click to deselect. Then, go to Selection > Delete Selected Chunks (Ctrl+D). Save the changes. This step optimizes your world for conversion.

Step 4: Convert with MCC Tool Chest

Now, launch MCC Tool Chest (Bedrock Edition). Open a new blank Bedrock world (create one if needed). Then, go to Tools > Convert > To Bedrock. When prompted, select your Java world. If MCC can't find it automatically, point it to your Java world folder. Leave all options as default and click Convert. The conversion may take a while for large worlds. Once complete, you'll see a "Conversion Completed" message. Click Close, then go to File > Save As > New World, name your converted world, and click OK. Your world is now in Bedrock format!

Step 5: Enable Ray Tracing with a PBR Resource Pack

To experience ray tracing, you need a PBR resource pack embedded in your world. After conversion, navigate to your Bedrock world folder and ensure it contains a resource pack. If not, download one from the Minecraft Marketplace or create your own. Then, open the resource pack's manifest.json file and add the following before the last closing bracket:

"capabilities": [
  "raytracing"
]

This enables ray tracing for the world. Save the file. Now, launch Minecraft with RTX (via Xbox Insider Hub), go to your world's settings, and activate the resource pack under "My Packs." Click Play to load into your world with ray tracing enabled.

Final Thoughts: Bringing Your World into the RTX Era

Converting your Java world to Bedrock for Minecraft with RTX opens up a new dimension of visual fidelity. While the process involves multiple tools and steps, the payoff—experiencing your creations with path-traced lighting and PBR textures—is worth it. Remember to back up your worlds before any major changes, and don't hesitate to experiment with different resource packs to enhance your RTX experience. With ray tracing and DLSS, your world will look more immersive than ever. So go ahead, convert, and explore your world in a whole new light.
