Mbd2Thread is an add-on mod for Multiblocked2 (MBD2). It introduces a “thread-like” execution model for machine recipe logic (parallel / queued execution) and improves the localization experience in the editor’s graph/node system, making complex machine workflows easier to build and maintain.

Main Features

Recipe Thread Trait
- Adds configurable “threads” to a single machine, allowing recipes to run in parallel or be scheduled per thread (useful for multi-lane machines and complex production pipelines).
- Supports per-thread display texts and whitelist/blacklist controls to decide which recipes can run on specific threads.
- Includes UI support: display thread status, progress and hover details in the machine UI (template can be generated and bound in the editor).
Fuel Adaptation
- When enabled, the mod can optionally consume any item with a burn time from the specified “fuel slot”, and automatically fill fuel time so the machine can keep running.
- This feature is disabled by default. Leaving the fuel slot name empty will also disable it to avoid unintended behavior.
- Config location: machine `recipe_thread` trait (thread trait) config
- `Fuel Adaptation Switch`
- `Fuel Slot Name`
Editor Graph Localization Improvements
- Adds/fixes translations for common graph UI texts (node groups, machine event names, some port labels, search label, etc.) to improve readability.
Energy Feature at the Level of Long.MAX_VALUE
A new feature has been added to enable MBD2 machines to utilize FE energy exceeding the int limit for input/output/storage, with recipe support included.

Core Fixes & Improvements
- Editor Block State Auto-Capture
Fixed an issue where “Generate State” in the MBD2 editor failed to record BlockState. Clicking “Generate State” now accurately captures all block properties (orientation, toggles, numeric values, etc.), ensuring complete structure data.
- Precise Builder Placement
Resolved a problem where the multiblock builder tool did not place blocks with the correct states. The builder now restores block states exactly as specified, eliminating orientation errors or missing attributes that could break structures.
- Build Order Refactor
Optimized the automated build sequence so fluid blocks (e.g., water, lava) are always placed last. This avoids premature fluid spread before the frame is complete, improving stability and logical consistency for complex builds.
- New Features

Material Repository Binding
The multiblock builder tool now supports easy binding of material supply repositories.
- How to use: Hold Shift and right-click any container (e.g., chest, barrel) or fluid storage device while holding the builder.
- Effect: The bound device becomes a “material repository” for the builder. During construction, the builder automatically pulls required items/fluids from it, removing manual hauling and making survival-mode builds far simpler.
- The MBD tool now opens a radial menu with the R key (customizable) to switch modes. A slow build mode has also been added to prevent lag when building large structures.
