BlockForm+
by KI10
With BlockForm+, players and creators can hold item forms of blocks that vanilla Minecraft normally keeps out of inventories, such as End Portal, Nether Portal, Cave Air and Void Air.
What it does
The mod is a lightweight Fabric addition that gives item forms to blocks which cannot be obtained in normal play. Among them are the End Portal and Nether Portal blocks, Cave Air, Void Air and other non-item blocks that vanilla Minecraft does not offer as items. Items are registered safely and balanced for creative use, so a world's existing content is left as it is.
The mod also includes special technical blocks and structures. Map makers, modpack developers and creators can place these technical blocks directly, and they work with custom systems and datapacks. Builds suit creative work, map building and testing new ideas. BlockForm+ is compatible with other mods, and its source code is public under the GNU Lesser General Public License v3.0 only, so the code is open source.
Installation requires Fabric. The server must run the mod, while players may add it for the item forms, so the mod works on a server alone and the client can join without it. Files are published for 1.21 only, with 0.0.1 as the latest Fabric file, released 2025-11-22.
