Crystalix
by Satherov
Crystalix adds a set of colored glass blocks for NeoForge, where one block can hold many different functions depending on its properties.
What it does
A single glass block in Crystalix can take on a wide set of properties, which determine how it looks and behaves. Using a wand, players cycle through the possible properties and apply them to other blocks. The mod's glass comes in three variants, and one of them is invisible, so builders get a block with the chosen properties but no visual surface. Unlike earlier releases, the number of block variants was cut sharply starting with version 2.3.0.
Crouching lets a player edit connecting blocks in one action, and holding Ctrl limits an edit so that only the color property is applied. Pressing X copies the properties of the block being targeted with the wand. A config window opens with V by default, and left-click scrolling down cycles forward while right-click scrolling up cycles backward. Mixed properties can be matched when a builder wants a combination, and color can be applied to glass in a practically unlimited number of combinations.
Crystalix is built for NeoForge and targets 1.21.1 only, with the latest file 3.0.0 for 1.21.1, published on 2026-03-27. The code is under the GNU Lesser General Public License v3.0 or later, and the project is open source, with a public source code repository and issue tracker. Servers that run it need every player to install it too.
