Beam Blocks
Beam Blocks adds a set of structural beam blocks for building floors, ceilings and pillars, with a wood palette that covers pale birch, deep dark oak, cherry and bamboo.
What it does
The mod adds a beams world for builders who need support that vanilla fences and walls do not give. Beams are cut to align on the block grid, so horizontal supports, vertical pillars and ceiling frameworks line up without offsets. Its smart placement helps the blocks snap into the right orientation as they are set down.
Each wood type comes with its own beam variant, covering the common oak and spruce family as well as pale birch, deep dark oak, cherry and bamboo. The textures follow vanilla patterns, so they stay consistent in 32x and 64x resource packs. Beam Blocks is built to keep frame-heavy builds such as medieval halls, underground mines and industrial zones from slowing the game.
Files exist for Fabric, Forge and NeoForge. The client and server environment means both the server and every player need the mod. Game versions run 1.20.1 – 1.21.8, with the latest 1.0.1 file for 1.21.8 on Fabric and NeoForge and for 1.20.1 on Forge. The mod is released under All rights reserved and is not open source.
