Universal Multiblock Viewer 0.5

Universal Multiblock Viewer 0.5 adds Creative-mode structure placement and in-game guide capture tools for players and modpack authors.

Build Here

• Added the green B button to the lower-left of the 3D preview when playing in Creative mode.
• Preview the currently selected structure at the block you are looking at before placing it.
• The preview uses the selected variant, visible optional blocks, and chosen alternatives.
• Left click places the structure and right click cancels the preview.
• Mouse wheel rotates the preview. Ctrl + mouse wheel moves it up or down.
• Placement only replaces air. If any target block is occupied, the whole placement is cancelled safely.
• Added /umv undo to remove your most recent Build Here placement. Blocks changed after placement are preserved.
• Build Here does not consume items or activate machines, multiblocks, or rituals.

In-Game Guide Capture

• Added OP-only /umv capture commands for pack authors using KubeJS.
• Mark two corners with /umv corner1 and /umv corner2.
• Set the main lookup block with /umv master U, /umv master R, or /umv master both.
• Save a new definition with /umv save namespace file_name.
• New KubeJS namespace folders are created automatically when needed.
• UMV now explains when KubeJS is required instead of creating an unusable file.

Reloading Guides

• Added /umv reload to refresh resources and update UMV guide pages in JEI without restarting Minecraft.
• EMI does not expose public runtime guide registration, so a restart is still required to add a new guide page in EMI.

Compatibility

Build Here is Creative-only. In multiplayer, install Universal Multiblock Viewer on both the client and server for placement and undo to work.
