MCreator 2026.1 – Biggest mod making update so far

We have made the biggest update to date once again! It changes Minecraft modding with many new features, fixes, and improvements. Read on!

Minecraft Bedrock edition upgrades

The 2026.1 update brings massive improvements for Minecraft Bedrock Edition add-on creators. We've completely overhauled how you build Bedrock content by introducing a dedicated visual scripting system, customized element types, custom block models, and expanded rotational controls. Additionally, support for custom worldgen structures placed with procedures or commands was added too. This update marks our biggest leap forward in streamlining Bedrock development.

Visual scripting for Minecraft add-ons

We've added a new "script" mod element that functions similarly to procedures, but is natively built and specialized for Minecraft Bedrock Edition. The system uses Blockly for the same Scratch-like interface as we use for procedures.

This system includes an extensive library of new script blocks covering Minecraft components, basic math, logic, text, and flow blocks. You can add items to entities, run commands, trigger explosions, play sounds, spawn entities, and send chat messages. These actions are driven by newly added global, block, and item script triggers, such as "player interacts with block" or "item consumed." See an example below to see how one can make blocks with custom functionality, such as a time fuse in this example.

Dedicated Bedrock element types

To better support the features of Bedrock add-ons (that differ in many areas compared to the Minecraft Java Edition), we created special Bedrock block and Bedrock item mod element types.

You can find the new parameters added showcased below. We have added parameters such as creative tab, hide in commands, generation shape, rotation type, render method, tint method, and more!

MCreator 2026.1 also adds new Bedrock item parameters, including rarity, tool-like rendering, creative tab, item animation, use result item, movement modifier, hide in commands, off-hand use, fuel duration, despawn when dropped, is stacked by data, and more. Check them out in the showcase below.

Block rotations

We've added a specific rotation type parameter to the new Bedrock block element, allowing one to easily define directional placement rules for custom blocks in a very similar way to the Java Edition blocks.

Custom block models

You are no longer limited to standard block shapes in your add-ons. MCreator now supports importing custom block JSON geometry models directly for Bedrock Edition.

Additionally, we added new built-in block model types: single texture and cross models. Check them out in the demo below!

Refreshed look and feel

The workspace has received a major visual overhaul to align with modern IDE tools. We redesigned the default UI dark theme to provide better contrast and usability. Code and console editors now use JetBrains Mono as the default monospaced font, complete with support for enabling font ligatures to make reading code much easier.

Docking system

Navigating the tools and utilities in your MCreator workspaces is now much easier with our new docking system. We added a collapsible side strip that gives you quick, persistent access to the project browser, console, debugger, and code viewer without cluttering your main window. Plugins can extend the collapsible side strip with custom docks.

Chromium-based Blockly editor

In the past, we have used JavaFX webview to render Blockly editor, used for editing procedures, AI tasks, world gen features, and many other components in MCreator. JavaFX uses a WebKit-based editor that is slightly outdated by today's standards, has rendering issues on some computers, becomes slow with large procedures, and even crashes on some computers.

There are very few alternatives, but the main one is the JCEF framework, which uses the CEF library, which is a library that allows one to embed the Chromium webview engine in Java applications. This new engine will make Blockly editing faster, and one can now smoothly edit procedure setups with thousands of blocks without lag or crashes. Additionally, the transparent background for custom images now works much faster and also supports Linux!

Together with the new Blockly webview engine, we have also updated the Blockly panel to fit with the new color scheme and the flattened look.

Block state support

One of the most requested features for Minecraft Java edition modding is here: custom blocks now support block states! You can dynamically change block model, textures, and bounding box based on state property values.

Below, you can see how custom block states are defined. Inspired by item states, one defines conditions, and then textures, models, bounding boxes, and more. Minecraft requires all combinations of used state properties to be defined, and MCreator auto-fills the missing state combinations for you!

We have also added support for controlling block luminance using procedures and block states, giving you total control over dynamic lighting based on the block state.

Special entity mod element type

We were looking into the best way to allow the creation of custom boats. As a solution to the problem, we have introduced a special entity mod element type specifically designed to allow the easy creation of custom boats, handling the complex underlying vehicle mechanics automatically. Right now, one can make boats and chest boats, but more special entity types are to come in the future!

Below you can see a custom Minecraft stone boat in action - make any boat type you want!

New wood pack options

The wood pack maker tool has been significantly expanded to save you even more time. It now automatically generates standard signs, hanging signs, and boats for your custom wood types. It also supports wood bark color, features improved textures, and automatically makes the generated leaves compostable.

Custom Minecraft signs

To fully support the new wood pack features, we added dedicated block bases for both standard "sign" and "hanging sign" block types, allowing text input and formatting just like vanilla wood variants.

One can make support for standard signs as seen above, hanging signs as shown below, or both types by making two blocks with a block base, once a regular sign and once a hanging sign.

Here you can see how the sign block base can be defined. For convenience, you can use the wood pack maker tool to create sign configurations and textures for you!

Item and tool attribute modifiers

Balancing your mods is now more precise. We added an option for custom tools and items to directly specify their attribute modifiers in their setup. Additionally, custom items with melee damage can now specify attack speed, while custom tools, items, and armor can now define rarity and repair items.

Split item inventory and GUI open parameters

Binding a GUI to an item is no longer a rigid interaction. Opening the bound GUI of a custom item is now entirely optional and can be conditionally controlled using logic procedures.

Particle orientation control

Visual effects are getting an upgrade. The rotation of custom Minecraft particles can now be dynamically controlled using vector procedures. If you want a more uniform look, we also added an option to disable particle size variation.

Translucent armor option

You can now create custom Minecraft armor with translucent parts, making things like visors, glasses, crystal gear, and more possible. Armor translucency is an optional feature that should only be enabled on armor that uses it, for performance reasons.

Cave biomes in custom dimensions

Custom Minecraft dimensions can now feature complex underground ecosystems. We added support for specifying cave biomes directly in custom dimensions, controlled by a new custom cave biome depth range parameter (that also works with overworld custom cave biomes) to dictate exactly where they generate.

Custom leaves particles

Make your custom biomes feel alive with falling leaves. You can now configure a specific particle type and spawn chance directly within the custom leaves block base.

Custom command autocomplete suggestions

We added a new command argument type: resource location with suggestion. It enables native autocomplete drop-downs when typing your commands in-game, as shown in the example below. You can now make your custom Minecraft commands feel more integrated and vanilla-like.

More advancement options

We have added new advancement triggers for when a "player crafts recipe" or "player unlocks recipe." We also introduced a highly useful "any item in the list" advancement item selector, which can be used with certain advancement triggers. We plan to add more triggers that support this feature in the future, too!

More procedure blocks

We did not forget about procedures. As with every update, we try to add more of them, and this update is no exception. It adds many new, very useful procedure blocks. We added new entity procedure blocks to retrieve the number of ticks an entity has existed, grab their session ID, or fetch an entity via a UUID string. See examples of this in the image below.

We also added blocks to set and get NBT itemstack tags across items, blocks, and entities. While we encourage the use of inventory system where possible, those procedure blocks come in handy for the edge cases where the inventory system does not cut it.

To help with complex spatial calculations where data persistence is needed, we have also introduced global scope support for vector variables. One can now store things like locations and rotations in global variables.

Image maker improvements

The built-in image editor is more capable with the addition of vertical and horizontal flip tools. We also improved the layer resize canvas adaptation algorithm and optimized image downsizing across the entire software (not just the image editor, but downsizing in general).

Improved UI performance

Working in MCreator is noticeably faster and more stable. Not only, as already mentioned, we also migrated Blockly to a Chromium/JCEF WebView, which significantly improves Blockly performance, but we also covered other performance areas. We fixed a bug that caused UI lag when using background images, improved variable and localization editing speed, and much more! A very welcome improvement for power users with large workspaces with thousands or even tens of thousands of mod elements.

Generated code improvements

We have applied several improvements to the generated code to make mods faster, more compatible, and more efficient overall. As part of this optimization, we improved the generated code of the block mod element to override fewer methods when possible, keeping your mod's footprint lighter and cleaner. Additionally, we improved the wait procedure block to cause significantly less lag when used often, ensuring your more complex custom logic runs smoothly in-game without impacting performance.

Release notes

• Existing blocks may have custom light opacity handling disabled by the converter if it is estimated that it was not needed
• Flying entities now fly with the correct speed. If you set very high flying speeds in an attempt to fix this bug, entities will fly very fast, and the movement speed parameter may need to be manually adjusted.
• Addon blocks, tools, and items are converted to Bedrock variants of blocks and items for more specialized editors that match Minecraft Bedrock edition features
• Removed custom biomes from addons, as Minecraft Bedrock Edition no longer supports them at this time
• [Plugins] API plugins can now specify a version range parameter for mod dependencies they declare
