RXB-Kit
by Roxanne
RXB-Kit by Roxanne is a Forge and NeoForge technology mod that adds lightweight 16x16 building blocks, nuclear power parts and optional economy items.
What it does
Roxanne built the kit to help players with creative building projects, such as custom maps. Its blocks and items can be crafted, and the set includes detailed foliage along with a working speaker kit, nuclear power content and building blocks in a 16x16 style. An optional in-game economy system lets players acquire some materials through the kit's trading features.
Installation covers the server and each player's game. Installation is for Forge or NeoForge only, with files for 1.19.2 – 1.21.1 across 4 release versions, and the mod is released under All rights reserved and is not open source. Nyoldarria requires it.

How it compares
Create Nuclear is open source under the GNU Lesser General Public License v3.0 only and covers Fabric, Forge and NeoForge for 1.20.1 – 1.21.1. Create Nuclear Radiation is open source under the MIT License and runs on Forge and NeoForge for 1.20.1 – 1.21.1, so it is the closer match for NeoForge-only setups.

Feel free to include in any of your awesome Modpacks! As a builder, this mod was originally made to help myself in my creative endeavours making custom maps, but has now been reworked to be survival friendly too, with quite a few interesting gameplay mechanics.
