Scipi's Lights
by Scipione
Scipi's Lights introduces glowing glass blocks and glowing glass panes in all 16 dye colors, plus a colorless version, and targets NeoForge 1.21.1.
What it does
Each glowing glass block and pane comes in two light strengths. The soft version gives light level 8 and the strong version gives light level 15. Players can craft vanilla stained glass and plain glass panes into lit equivalents, letting a builder replace existing windows with light sources without gathering new materials.
Every glowing block and pane carries the tags scipislights:glowing_glass_blocks and scipislights:glowing_glass_panes, which lets other mods and datapacks address the full collection in one reference. Its glowing glass stays a normal glass block for copycat-style mods, which is the gap the author describes: many glowing glass mods fail inside copycat blocks because the light source is lost. Scipi's Lights keeps the glass plain and self-contained, so it works inside copycat blocks the same way ordinary glass does.
The mod is a NeoForge build for Minecraft 1.21.1 and is released under the MIT License, so the source code is open source. It is installed on the client and the server alike, and both sides must run it. An optional connected texture support with Fusion is included. Public links exist for the source code and the issue tracker.
Key features
Sixteen dye colors
Glowing glass blocks and panes exist in each of the 16 dye colors, plus a colorless variant.
Two light strengths
A soft variant emits light level 8 and a strong variant emits light level 15, for lighting that suits a room or a feature.
Vanilla glass recipes
Converting vanilla stained glass and glass panes into glowing versions is handled by recipes, so the route from ordinary glass to a light source stays brief.
Copycat compatibility
The glowing glass keeps its light source inside copycat-type blocks, where many other glowing glass mods lose it.
Connected textures
Optional connected texture support works through Fusion, so adjacent glowing panes join visually.

How it compares
Illuminated Glass is also a NeoForge 1.21.1 glass mod that is installed on both client and server, with an MIT License, but it is not open source in the same sense; Scipi's Lights is open source under the MIT License. Horizontal Panes covers Fabric and NeoForge with the same client and server environment and an MIT License, and it is open source, which makes it the closest match in license terms. STAINED is a NeoForge 1.21.1 mod that runs on the client alone, while Scipi's Lights needs both sides.

What the author says
A small NeoForge mod for Minecraft 1.21.1 that adds glowing glass. There are many glass mods out there, but most of them run into the same problem: the glowing glass isn't compatible with mods like Copycats, so you can't use it as a light source inside a copycat block. Scipi's-Lights solves that by adding plain…
