SecondDawnBlocks
by ShardSolar
SecondDawnBlocks adds large-scale sci-fi building blocks for Fabric, aimed at players who build starships, space stations and corridors.
What it does
The blocks cover full families: stairs, slabs, walls, trapdoors and connected panels, along with vertical slabs, layer blocks, corner stairs and quarter blocks for horizontal and vertical builds. Its panel system includes hundreds of distinct sci-fi textures, so interiors can mix surfaces without repeating one pattern across a whole wall.
Every material set uses a coordinated palette and a clean, industrial, futuristic style, so different pieces stay consistent when they share a room or a hull. The mod is meant for building freedom rather than gameplay mechanics, and its blocks keep the vanilla block shapes and behavior, so they combine with ordinary blocks and existing structures without special handling.
SecondDawnBlocks pairs with roleplay systems, and the author names SecondDawnRP as a companion. It needs the Fabric loader on Minecraft 1.21.1, and it must be installed on both the client and the server, so every player on a server that runs it needs it too. The code is not open source, and the project is released under All rights reserved, while its source code is publicly available.

How it compares
Vanilla+ Verticals is a Fabric mod for 1.21.1 – 1.21.10 that targets vertical blocks, is shipped under the Creative Commons Attribution Non Commercial 4.0 license and is not open source. More Block Variations (Vertical Slabs) is a Fabric-only mod for 1.21.3 with an MIT License and open source code, so it differs in version range and license from SecondDawnBlocks.
