- Download the jar for your loader and Minecraft version.
Or let BlockDesigner do it: BlockCompanion Plugin's Install mod... puts the right jar into a game's
modsfolder. - Put it in your
modsfolder. - Put your BlockDesigner projects (
.bdproj) and schematics in<game folder>/blockcompanion/schematics. The folder is made the first time you start the game, and the load screen has an Open folder button.
Put blockcompanion-paper-<version>.jar in the server's plugins folder and restart. The same jar works on Paper and Spigot. See Server Plugin.
Updates are manual. BlockCompanion never contacts the internet or downloads anything. Get new versions from CurseForge or the GitHub releases page and replace the jar.
