Using Plugins

doole edited this page Oct 2, 2026 · 1 revision

Using plugins

Plugins are .jar files that add schematic formats, exporters, importers, menu actions, /commands, transforms with a live preview, side panels and tools.

Plugins run with the same access as BlockDesigner itself, so only install ones you trust.

The Plugins window

Open it from the Plugins (puzzle icon) menu with Manage plugins.... Each plugin is a card with its status, a settings button, Turn on / Turn off, uninstall and its log. You can install, enable or disable, reload and uninstall plugins there.

Installing a plugin

  • Pick it under Suggested to install. It lists the BlockDesigner team's plugins you don't have yet, each with an Install button that downloads its newest release.
  • Or download the plugin's .jar from its releases page and drop it on the drop box in the window. You can also click the drop box to pick the file.

Official plugins

Each lives in its own repository and is released separately from BlockDesigner.

Plugin What it does Needs
BlockCompanion Plugin (formerly Resource Tracker; installed with BlockDesigner) Links BlockDesigner to the BlockCompanion Minecraft mod: send projects into the game and edit builds from it. Also the materials a build needs as items (stacks and shulker boxes), what you have gathered and what is left, saved with each project 0.4.24
Palette Tools Weathering, palette swap and gradient transforms, a Palette panel, a colour palette exporter, a pixel art importer and a Wall tool 0.4.24

"Needs" is the BlockDesigner version the plugin requires.

BlockDesigner installs the BlockCompanion Plugin, switched on, the first time it starts. If you uninstall or switch it off, it stays that way.

Using a plugin

  • Each running plugin has a tab on the right with its pages. The info button on the tab shows what it adds.
  • A plugin's settings are on its page under Plugins in Settings.
  • Its tools and Plugins-menu actions can be given keys in Settings > Keybinds.
  • When two plugins can import the same kind of file, Import asks which one to use.

Updates

Check for updates in the Plugins window updates every plugin.
