The 2nd snapshot of MCreator 2026.1 is here. This is very likely the biggest snapshot we released to date in terms of features. Read on!
Refreshed look
One of the most noticeable changes is a refreshed look. MCreator now contains a side button strip with toggles to enable and disable "docks" like the project browser, console, debugger, and generated code viewer. Layout is stored per-workspace, so you don't need to set up your desired layout every time from the scratch.
The color scheme of the default theme has also been darkened, to work better on OLED monitors with nicer contrast. The whole UI has also been slightly flattened for a more modern look.
New Blockly webview engine
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.
The refreshed look was also updated to work seamlessly with the background images. Side button strip becomes transparent, and the transparency of tabs has also been improved to work better when background images are used.

Release notes
- 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 and items are converted to Bedrock variants of blocks and items for a 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

Comments
Suggestions:
Dimension overhaul!
- Instead of continentalness, erosion, etc properties being defined in the biomes, they are defined in the dimension, like how vanilla does it. This would come with overhaul of the biome spawning, more like an entry list rather than a raw list. This includes biome size if it exists, and depth, allowing for cave biomes and sky biomes in any dimension.
- End biomes! A plugin did it, so it should be doable.
- Surface rules. We need more than just a top, dirt, and filler layer. This would allow for the implementation of deepslate layers and deeper dirt layers, and more. Surface rules can be applied to only be in certain biomes (like sandstone only for deserts) or for all biomes (like the deepslate layer).
- More features! It seems a lot of vanilla features are missing, such as chorus plants.
- Noise settings. Oh my gosh, this would be so cool! There would be normal presets (nether, end, overworld, maybe floating islands preset?) and a blockly or entry editor that is kinda like the JSON used in dimensions. With presets if its blockly of course. One of the presets could take the floating islands noise from the 2024 april fools update, as it is like a vertical version of end islands.
- Zombie, and skeleton entity models. Self explanitory. And maybe a guide for the bones for models but I think that can be obtained from the minecraft wiki
- More field explanations. A lot of fields are unexplained and ambiguous.
- Block replacers in structures. Structures and jigsaw components can have a custom ruleset for having random blocks replaced, such as in Strongholds with mossy cobble. Doesn't have to be complex, a random chance of repalcing a block is good.
- If custom noise settings and editors cannot be implemented, maybe there would be a feature of locking a certain file, but not its element. Possibly even a certain section of the file. Locked files can be edited but won't be overwritten.
Overall, I like this update! Signs and boats are very good!
Ok, i'll admit i didn't ready all of the changelog before writing this, but I just realized they let you set cave biomes depth and set it to be in custom dimensions. Unsure if it lets you set different depths for dimensions, but that could be implemented with the custom biome editor above. And to note, the biomes are still seperate, but their generation would be handled by dimensions.
I would like to suggest several possible improvements for MCreator.
First idea:
A new variable type that can store a generated entity instance. This would allow procedures to directly access and modify the entity after it is created.
Second idea:
A procedure block that returns the result item of a crafting or smelting process.
Third idea:
A procedure block that opens a trading interface similar to the vanilla trading system. The trades and conditions should be configurable.
Fourth idea:
Better control over GUI element positioning and built-in scroll bar support.
Sorry
