Undead Sunscreen
by Luc1fer1o
Undead Sunscreen, a NeoForge server mod for Minecraft 1.21.1, changes which mobs burn in daylight by making daylight burning opt-in through a config list.
What it does
By default the mod stops mobs from igniting in daylight, so zombies, skeletons and other undead no longer burn as they do in vanilla. A list called sunburnBlacklist in the config holds the entity IDs that should keep the vanilla behavior, written in full form such as minecraft:zombie and minecraft:skeleton. Mobs that are not on the list are protected, and an empty list means the protection applies to every mob.
The mod also works with modded mobs, since any entity ID can be added to the list. Fire from lava, campfires and the Fire Aspect enchantment is not affected, because only daylight burning is changed. Undead Sunscreen is server-side only, so players join without installing it, and it is published for NeoForge on 1.21.1 with the 1.0.0 file from 2026-07-02. It is released under All rights reserved and is not open source.
Key features
Daylight protection by default
Mobs that would normally catch fire in sunlight are protected unless their entity ID is listed in the config.
Configurable blacklist
The sunburnBlacklist setting accepts full entity IDs, so server owners choose which mobs keep vanilla daylight burning.
Modded mob support
Entity IDs from other mods can be added to the same list, not only the vanilla zombies and skeletons.
Other fire sources unchanged
Lava, campfires and the Fire Aspect enchantment still set mobs on fire as before, because only daylight burning is affected.

How it compares
Protect Mobs From Daylight does a similar job on Fabric and Forge for 1.19 – 1.20.2, and it is server-side only under the GNU General Public License v3.0 only, so it is open source. Mob Sunscreen also covers NeoForge, for 1.12.2 – 26.2, under the MIT License, but it is client and server, so every player must install it. Daylight Mobs Reborn is Fabric only, for 1.16.5 – 26.2, server-side only and under the Apache License 2.0. Undead Sunscreen sits between these options: it is NeoForge only, server-side only and not open source.

Undead Sunscreen changes daylight burning behavior for mobs in Minecraft 1.21.1 on NeoForge. By default, the mod protects every mob from vanilla daylight sunburn.
