Radioactive Skulls
by Roboter007
Radioactive Skulls, a NeoForge client-side utility, changes how skulls are rendered and displayed in the world.
What it does
Skulls are drawn differently once the mod is active: the way a skull's model and texture appear on screen is altered on the client. Because the change lives entirely in rendering, no new blocks, recipes or entities are added to the game, and the world data stays as it was.
The mod has no server component. Only the player's client needs it, so a server owner can run vanilla server software and players who want the altered skull display can install the mod on their own game. The code is open source under the GNU General Public License v2.0 or later, and the author publishes issues on GitHub. Files target 1.21.10 – 1.21.11, and the latest NeoForge file, 0.1.2, is for 1.21.11.
The project's author text recommends a stable setup: experimental game options should be turned off before the mod is used, and problems are to be reported on the GitHub issue tracker so they can be traced to the rendering code.
Key features
Altered skull rendering
Skulls appear differently on screen, with the rendering of their display changed on the client side.
Custom render type
The mod assigns skulls their own render type, which controls how they are drawn alongside other blocks.
Client-only change
The effect applies only on the player's side, so the server keeps its normal skull data.
Public issue tracker
Source code and an issue tracker are linked publicly, so rendering problems can be reported and followed.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Who it’s for: Players on NeoForge 1.21.11 who want a different skull appearance, and players who test rendering changes and report bugs to the author.
How it compares
Witherify skull is a NeoForge mod for 1.21 – 1.21.11 that runs on client and server, unlike Radioactive Skulls, which is client-side only. Its license is CC0 1.0 Universal, and it is open source. Indicatia is client-side only like Radioactive Skulls, but it is published for Fabric, Forge and NeoForge across 1.18.2 – 26.3 under the MIT License and is open source. Wither Skull Barter is server required with optional client support, works on Fabric, NeoForge and Quilt for 1.21.11, and is not open source under CC0 1.0 Universal.

What the author says
This mod makes it possible to see skulls/heads through blocks. There are also some experimental options that could lead to a crash and are therefore disabled by default. These can be turned on in the config menu. As this can be considered cheating on some servers, I am not responsible for any bans related to this…
