Experimental Features in Minecraft: Bedrock Edition

• 5 contributors

With each retail version of Minecraft: Bedrock Edition, there are a few features that are currently in an experimental state. Experimental Features can be toggled on for creators who are interested in testing the latest features offered in the preview, and retail versions of Minecraft.

The Experiments toggle list is subject to frequent changes and could have entirely different options from the ones in your own version of Minecraft. Also, the screen shots shown here might look different.

Experimental Features available in Minecraft: Bedrock Edition

There are two sets of experimental features available, depending on whether you are using a retail version of Minecraft or the latest version of Minecraft Preview.

These are the currently available Experimental toggles in the 1.20.81 retail build at the time of this writing.

GAMEPLAY - Change the way your world works

ADD-ON CREATORS - For creators of game packs and other add-ons

These are the currently available Experimental toggles in the 1.21.10 preview build at the time of this writing.

How do I activate an Experimental Features toggle for my world?

You can activate an experimental toggle for any of your new or existing worlds.

Activating experimental features that are still under development means that your world might crash, break, or not work with future updates.

If you're planning to build content that you want to share with the community, it would be best to do it in a non-experimental world.

Toggle Experimental Features in a New World

If you are building a new world from scratch to test experimental features, you can toggle which features you want enabled in the Game Settings.

Under Game settings, navigate down to Experiments and select a toggle to enable the feature.

When you get the popup asking if you're sure, select Turn on Experiments anyway .

Toggle Experimental Features in an Existing World

If you want to add experimental features to an existing world, open that world's game settings and activate the toggles just like you would for a new world.

A copy of your world will be generated automatically after you activate an experimental feature toggle. You can also manually create copies of your world as an extra precaution, in case something goes wrong.

After you select Activate Experiments , a copy of your existing world will be created. The copy will have the same name as the original world with "Copy of..." added in front of it.

Verify that the World has Experimental Features Enabled

After you've created a world that has an experimental feature toggle enabled, your world will get a tag next to the game mode in your Worlds list that says Experimental .

Another way to identify if your world is using experimental toggles is to visit the settings for your world. In the Game world settings, scroll down to the Experiments section to see which experiments are enabled.

Worlds that use experimental features cannot be restored to a non-experimental state.

I opened my world in 20w21a and in every snapshot and release after that, it keeps saying:

"Worlds using Experimental Settings are not supported

This world uses experimental settings that could stop working at any time. We cannot guarantee it will load or work. Here be dragons!"

Those experimental settings probably come from the fact that they've added custom world generation in that snapshot, which probably changed something in the way the map generates, or the way the file is written.

I want to change my world settings back to default , to make sure my map (which I've spent too many hours on) keeps on working in the future. I'm pretty good with modifying JSON files and I've used NBTexplorer many times in the past to change some things in my world. If anyone knows how to fix this, I need your help!

(I have backups of the world, but I've changed too many things around the world to start from my last backup, before 20w21a. If there is a file I could simply copy and paste from my latest backup (pre-20w21a) to my world (post-20w21a) to put the experimental settings back to the default settings, it would be great!)

Is it complaining about the experimental settings in 20w21a or are you trying to run it in some other version?

If it's working in 20w21a I'd say your best bet is to keep it there.

You almost certainly can't go back to an earlier version without corrupting the world, except by loading a backup, certainly make a backup before trying to run it in anything else.

If you can run it in the release of 1.16 (after making a backup) then try that.

This won't be any help in your current situation but you should never trust snapshots for worlds you care about, make a backup and accept that the snapshot is meant for temporary testing of the updates not for serious play.

It's most likely not just the settings themselves that would be a problem but the results on the world of running the game with those settings.

Hopefully somebody will come along that knows something about those experimental settings.

I can run it in 1.16 but it keeps saying that warning: " This world uses experimental settings that could stop working at any time".

This is why I want to find a fix to put it back to how it was, to the default settings and not the experimental settings.

I found where the problem is:

In the section where you choose your world, click edit and now you have the option to do "Export World Generation Settings". In the JSON files that it gives you, you get this section:

1) (For the world that wasn't in 20w21a)

{ "bonus_chest": false, "dimensions": { "minecraft:overworld": { "type": "minecraft:overworld", "generator": { "biome_source": { "seed": 3880217131079144221, "large_biomes": false, "type": "minecraft:vanilla_layered" }, "seed": 3880217131079144221, "settings": "minecraft:overworld", "type": "minecraft:noise" } },

2) BUT, on the version opened on 20w21a, it looks like this: (the part in purple is what changed)

{ "bonus_chest": false, "dimensions": { "minecraft:overworld": { "type": "minecraft:overworld", "generator": { "biome_source": { "seed": 3880217131079144221, "legacy_biome_init_layer": true, "large_biomes": false, "type": "minecraft:vanilla_layered" }, "seed": 3880217131079144221, "settings": "minecraft:overworld", "type": "minecraft:noise" } },

I made 2 new worlds, by importing both of the world generation settings ( the one that had not been in 20w21a and the one that did ) and the first world generation setting didn't give the warning while opening the world while the script from 20w21a still gave the warning on the new world.

Now, I just need to figure out in which file I can find this line in my world folder, so I can remove it after : "legacy_biome_init_layer": true,

legacy_biome_init_layer (Boolean): Whether the world was default_1_1 https://minecraft.gamepedia.com/Custom

TheMasterCaver's First World - possibly the most caved-out world in Minecraft history - includes world download. TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4. Why do I still play in 1.6.4?

Please forgive me if I missed something; this page has a lot to read!

I exported the "worldgen_settings_export.json" file from my world, and not only does it not contain "legacy_biome_init_layer", it is quite large at 14.7 kB, as opposed to what xylonn72 posted. I've been playing on this world for over 5 years, and this isn't the first time something got broken and I had to fix it with NBT's and JSON's, but I'm completely lost as to what needs to be edited! In case it matters, it's a custom map that I play Survival on, and the original can be found here: https://www.planetminecraft.com/project/eldaria-island---custom-terrain-mc-10---end-portal/ (last updated for MC 1.6)

As I read it xylon72 only posted a section of their JSON file, cut down to the relevant portion.

So, are you saying you are having the same problem even though you don't have the presumed offending line in your JSON file?

I also had this problem, but I believe it was caused by my having originally created the world using customised settings pre 1.13.

In any case, I had exactly the same warning message pop up every time I loaded the world in 1.16+ and also had the "legacy_biome_init_layer": true," line in my exported world generation settings .json. I found the location of the offending line using NBTExplorer inside: level.dat/Data/WorldGenSettings/dimensions/minecraft:overworld/generator/biome_source and simply deleted it.

Now the world loads without first presenting me with the warning message. Maybe this helps someone, idk

i have mods own that need experimental gameplay to work but i cant find it so i cant enable them can you add experimental options

• December 14, 2021 02:40

Hi Durcell Richardson ,  

Mods are not officially supported in Minecraft Education Edition, and there are no plans to add experimental game play. 

• December 17, 2021 22:49

Greetings Durcell from Dominick at Minecraft Education support!

I apologize for the confusion here. Minecraft: Education Edition does not support experimental gameplay. This helps keep Minecraft: Education Edition stable, as many of these features aren't designed for Education Edition.
