Discover the Ultimate Minecraft World Conversion Guide for Bedrock and Minecraft with RTX!
On April 16, 2020, Andrew Burnes, Kelsey Blanton, PearlescentMoon, and GeminiTay published a guide on how to convert your Minecraft Java world to the Bedrock format that is required for Minecraft with RTX. This process, however, is not perfect or foolproof, so it's essential to take backups of all worlds and files before you proceed.
It's imperative to note that this guide is unofficial, and we use third-party tools to perform the conversion. We cannot guarantee that the product of these conversions will be the ideal experience during the Minecraft with RTX Beta.
If you want a guide on how to create PBR-enhanced ray tracing-compatible textures, you can head here.
To commence the world conversion process, you'll need to have the latest builds of Minecraft for Java and Windows 10. Additionally, you will need some unofficially supported third-party tools and applications.
Here are the officially recommended apps and unofficial apps:
- Official Apps:
- Unofficial Apps:
1. MCC Tool Chest (Bedrock Edition): Download from here.
2. MCA Selector: Download from here.
3. Forge Installer: Download the latest version, which should correspond with the version number of Minecraft Java that you're using, e.g. "Forge 1.15.2," combined with Minecraft Java 1.15.2 (version number visible in the "Installations" tab on the Minecraft Java Launcher).
4. World Edit For Forge: Download the version that matches the build of Minecraft you're using, e.g. "WorldEdit 7.1.0 (Forge for MC 1.15.2)," for Minecraft Java 1.15.2.
To convert your world to a different format, you must access your world and game client files. The default locations for these files are as follows:
- For Minecraft Bedrock (UWP) World Save Folder: %USERPROFILE%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds
- For Minecraft Java World Save Folder: %USERPROFILE%\AppData\Roaming\.minecraft\saves
Before converting your world to Bedrock, make sure it runs on Minecraft Java 1.15.2 or newer by updating your software and creating a local backup. Open Minecraft Java 1.15.2 or newer and load the older world. Update it when prompted, enter the game, and save and quit.
If you use World Edit or World Edit Forge's features and schematics functions, follow the instructions below. Otherwise, skip to the MCASelector section.
First, open your old world using your current versions of Minecraft and other necessary tools. Use the // World Edit Forge commands to create a schematic of your build and save it to your .minecraft World Edit schematic folder. If you don't have one, generate the folder by creating a test schematic in single player. Then, backup your old files and install all up-to-date software.
Next, create a new blank world in Windows 10 Bedrock and load into it. Create a space where you can add the schematic if necessary. Save and quit, then load the newest version of Minecraft Java and create a new single-player world. Load your schematic and paste it into the desired location, making sure to select "Open To LAN" in the menu. Save and quit.
Follow the MCA Selector instructions below, using the new Java world with the pasted schematic, and then follow the MCC Tool Chest instructions. Once these steps are complete, open Windows 10 Bedrock and you will be able to see your creation at the selected coordinates.
Please note that the Minecraft Bedrock Edition may encounter errors when loading a converted world unless you use MCASelector. This tool allows you to quickly and easily delete troublesome chunks containing water, bubble columns, smooth stone, Redstone Links, and Nether Portal Links in bulk, saving you from having to manually re-edit those aspects of your world in Bedrock.
Void spaces (spaces with deleted chunks) will automatically populate with the correct Bedrock-specific chunks when converted, although you may need to manually tweak or update certain aspects of your world in-game. As always, it is recommended that you keep a backup of your Java world before beginning.
To use MCASelector:
1. Right-click on mcaselector-1.9.3.jar, or a newer version, and select "Open With..." Java.
2. In the app, click File > Open and navigate to the folder containing your world's .mca files (e.g. %USERPROFILE%\AppData\Roaming\.minecraft\saves\WorldName\region). Once you're in that folder, click "Select Folder".
3. The app will load the world, which can be navigated using the middle mouse button and zoomed with the mouse wheel.
a. Keep in mind that very large worlds might take a long time to render or may not load correctly.
4. Use the left mouse button to select chunks you don't want converted. Right-click to undo any accidental selections.
a. Advanced users can try the chunk filtering tool located under Tools, which simplifies identifying specific types of chunks.
5. Delete the selected chunks by clicking Selection > Delete Selected Chunks (Ctrl D).
6. A warning window will appear, informing you that many chunks are about to be deleted. Confirm and wait.
7. Your Java world will now be missing the deleted chunks:
8. Close MCA Selector. In case you discover after the conversion to Bedrock that some chunks were missed, you can still either manually edit the game or redo the steps in MCA Selector prior to converting.
9. Follow the MCC Tool Chest instructions below to convert the Java world to Bedrock.
Once you have updated and prepared your Java world, you can now initiate the conversion process to Windows 10 Bedrock format using MCC Tool Chest (Bedrock Edition). Be aware that once the conversion starts, there is no turning back, so it is important to back up all of your Java and Bedrock world files before beginning.
1. Install and open MCC Tool Chest (Bedrock Edition), also known as “MCC.”
2. Select File > Open and choose your new and completely blank world.
3. Click on Tools → Convert → To Bedrock
4. You will be prompted to select the Java world you want to convert to Bedrock:
Step 5: Choose the desired world for conversion and a new screen will appear.
a. Note: if the Java world folder cannot be found automatically, the following screen will be displayed first. Use the folder icon located on the upper right side, next to "Minecraft Java world folder," and specify the folder location, for example, %USERPROFILE%\AppData\Roaming\.minecraft\saves\WorldName\. Follow the ensuing prompts until you return to the conversion screen depicted below:
Step 6: All options should be left as the default. Then, click "Convert". The conversion process will begin (please be aware that this may take some time on larger worlds).
Step 7: Once completed, a "Conversion Completed" message will be displayed. Click "Close" and you will be returned to the main MCC window.
Step 8: The new window will look similar to the previous one, but now, select File → Save As → New World, name your converted Java to Bedrock world and click "OK".
Step 9: Your Java world will now be saved and accessible within Bedrock. If it is not visible, check %USERPROFILE%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds to confirm the world folder is present.
Step 10: Before proceeding further, take note of the following:
When you opt-in to the Xbox Insider Hub Minecraft with RTX Beta, the world may not be available for opening in Minecraft Bedrock for Windows 10, other Minecraft Bedrock betas in the Insider program, or the full non-beta version of Minecraft with RTX that is launching at a later date. Therefore, it is recommended that you create copies and backups of all worlds you wish to play in the Minecraft with RTX Beta to be able to restore them in other versions of Minecraft at a later date. You may need to uninstall Minecraft and/or the current Xbox Insider Minecraft Windows 10 Bedrock beta in order to download the Minecraft with RTX beta when joining the new beta. Make sure to back up any worlds you want to keep before signing up for the new beta or uninstalling old versions of the game, as the worlds may be deleted automatically when you uninstall the game. This may also apply to the worlds you have recently converted! Minecraft saved worlds can be found at:
- To retain the original formatting of the text, the following information is presented in bulleted form:
- - To locate your saved Minecraft worlds, navigate to either of the following file paths depending on the game version you've used in the past:
- Each folder in the minecraftWorlds directory represents a game world. Save your worlds in a different directory on your computer that's not inside the Minecraft directory.
- Alternatively, you can export worlds directly from Minecraft to your PC or laptop's desktop by following these steps:
- Hit the "Edit" pencil icon, then go to Play > click the Edit icon > scroll down on the new screen, press the "Export World" button.
- - Download and install the Minecraft with RTX Beta (see link in point 11).
- Once your world is converted to the Minecraft with RTX Beta, save it in the proper minecraftWorlds folder. Then, embed a PBR ray tracing resource pack within your converted world save folder. If you don't already have one, you can download a PBR capable resource pack from our servers. Alternatively, you can follow our guide on creating your own textures using the physically based rendering pipeline, if you wish to make one yourself (see link in point 12).
- Note that the contents of different resource packs may vary, as they can impact different aspects of the game other than just textures.
- To quickly access resource packs in-game in any world when enabling packs as in step 17, extract and move our resource packs (or your own) to %USERPROFILE%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\resource_packs.
- If you intend to share your worlds with PBR textures with others, so they can play and enjoy your ray-traced creations, it's recommended to embed resource packs directly into the world folders themselves.
For those interested in downloading, converting, and playing their own worlds with ray tracing and PBR textures, we recommend using the alternative location mentioned above.
If you've decided to create your own resource pack instead of using one of our four ready-made packs or another ray tracing pack, you will need to modify the manifest.json file in your pack using Notepad or a similar application. This file can be found at the following file path, depending on whether you opted for the alternative save location from step 13:
Copy and paste the following text to the manifest.json file before the final closed curly brace:
- "capabilities": [
Please note that the contents of your manifest.json file will differ from others.
Save and close the file, then reopen Minecraft with RTX Beta. Select "Play," then click the pencil Edit button to the right of your world in the list of available worlds. The "Resource Packs" option will be on the left-hand side of the screen; select it.
On the new screen that appears, click the button labelled "My Packs." You'll see the resource pack you embedded at step 13. If not, double-check your steps to fix the error. If you added more than one pack using the alternative method, you can select any of them. However, only one pack should be enabled at a time.
Click on the Resource Pack you added in the "My Packs" drop-down menu, then click the new "Activate" button to complete the process.
After adding your chosen resource pack, it will shift into the "Active" list. To disable any activated resource packs, simply expand this list. It's worth noting that while you can load multiple packs into one folder, enabling multiple packs simultaneously may result in errors, bugs, and glitches. Additionally, the current beta version has a limitation where textures may be down-rezzed if memory usage exceeds a certain threshold.
Once your resource pack is activated, click "Play" at the top left of the screen to enter your world. If you've installed our Minecraft with RTX Game Ready Driver or a newer version, you'll notice that ray tracing and DLSS 2.0 are automatically enabled. Your world will be illuminated in a brilliant new light with RTX turned on! If you're unsure if RTX is working, check the debug text at the top of your screen. In the current beta version, you'll see references to "D3D12 RTX" and "DLSS". Alternatively, hit Escape, go to Settings, select "Advanced Video," and ensure that both "DirectX Ray Tracing" and "Upscaling" (DLSS 2.0) are enabled.
If you don't see these options, or if there's an error message, something has gone wrong. Retrace your steps to catch any issues you may have missed. Once you've detected and corrected any block-related problems or errors, click "Save & Quit" rather than Alt F4'ing. This ensures that the in-game Resource Pack application is permanently implemented. Otherwise, you may have to repeat steps 16-20 each time you load Minecraft with RTX.
For subsequent worlds, simply copy the entire resource_pack sub-folder to your new world's folder, and follow steps 16-20. Alternatively, if you copied resource packs to the general folder mentioned in step 13 (%USERPROFILE%\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\resource_packs), click "Create New" in the "Play" screen, apply a resource pack as in steps 17-19, then click "Create" on the top left of the screen. This will load you straight into a new world with ray tracing, PBR textures, and NVIDIA DLSS 2.0 enabled.
Even though it can be daunting and complicated, world conversion can be quickly accomplished in minutes once you're familiar with the tools and workflow. You can bring all your Java worlds over to Bedrock and enhance them with ray tracing in Minecraft with RTX. For more details about the Minecraft with RTX beta, see our comprehensive and dedicated article.
Now that you've completed the process, use MCC to convert from Java to Windows 10 Bedrock format and load straight into Minecraft with RTX with PBR textures and ray tracing enabled.
