Minecraft 1.14.4 support, native waterlogging and recipe-book integration. Existing piece palettes, orientations and custom item data are kept when upgrading from 1.12.2. Saved item frames also load without stalling the world. See the release notes.

0.3.8.112021

  • Added the missing recipe-book unlocks for crafting and rebuilding pieces.
  • Made the next recipes appear while the crafting table is still open.
  • Keep recipe previews on the normal item model, including saved orientation variants.

0.3.7.112021

  • Use a shovel to turn ordinary dirt and grass steps and corners into paths. They keep their orientation, with the top lowered by one pixel.
  • Flattening a grass step or corner also turns the grass block beneath it into a path, using the shovel once for both changes.
  • Grass steps and corners keep their grass and snow edges, with grass left visible beneath partial pieces.
  • Rebuild two corners into one step and two steps into one slab by stacking them in the crafting grid. Matching BOP pieces work the same way.
  • Mineralogy rock steps and corners are now included when Mineralogy is installed. They rebuild into its native slabs; no separate add-on is needed. Saves made with the earlier test add-on keep their pieces and item data.
  • When Grass Slabs is installed, use 1.1.1.112021 or later for shared grass behaviour. Building Pieces still works on its own.

  • Tidied material names and word order across all 18 languages.
  • Kept recipes, registry IDs, metadata and world migration unchanged.

  • Kept posts at ends, corners, junctions and beneath blocks or torches above.
  • Matched selection and collision shapes to the wall profile and removed internal faces.
  • Kept existing materials, registry IDs, recipes and saved palette assignments unchanged.
  • Updated the BOP add-on wall models to use the same profile.

0.3.4.112021

  • Added a Sky's Building Pieces creative tab, including the vanilla pieces the mod reuses.
  • Made clear and stained glass walls continuous where the material and colour match. Borders remain at posts, exposed ends and colour changes.
  • Added raised posts at wall ends, corners, junctions and beneath blocks above. Straight glass runs have lower panels without a post in every block.
  • Matched glass-wall selection outlines to the panels and posts, and removed hidden internal glass faces.
  • Allowed ordinary and redstone torches on walls.
  • Kept existing pieces, palette assignments, recipes and world recovery unchanged.
