Armor CEM Compat
by Maguet
Armor CEM Compat keeps modded armor correct when a 3D armor resource pack is active on Fabric, so the pack's CEM rules stop distorting it.
What it does
A 3D armor resource pack written for vanilla armor can break modded armor: colors show dark patches and holes where the player's skin shows through, and the model is misplaced or squeezed. The mod adds a condition that makes EMF refresh the armor models in game, so this is corrected without editing the pack. It is client-side only, so a server does not need it.
The fix works on worn armor in the third-person view, which is where the bug appears. Inventory icons already look fine, and mob armor is covered too: armored undead and piglins, plus armor stands, are handled by the same rules. The mod requires [EMF] Entity Model Features and [ETF] Entity Texture Features, and is published for Fabric only, with the 1.1.0 file for 1.21.11 as the latest release, under the MIT License and open source.
Install a 3D armor pack as-is, and keep the pack's own rules unchanged. Drop the mod's jar into the mods folder next to the two required dependencies. Files were first published on 2026-09-04 and last updated on 2026-09-05.
Key features
Corrected modded armor
Armor from other mods keeps its intended model layout while a 3D armor resource pack is active.
In-game model refresh
An item condition makes EMF reload the armor models in game, so changes take effect without a restart.
Worn armor only
The fix targets worn armor in third-person views, and inventory icons are left as they are.
Mob armor covered
Armored undead, piglins and armor stands that wear modded armor are handled by the same rules.

Use cases
Who it’s for: Players who run a 3D armor resource pack in a modpack with custom armor tiers. Pack authors who want to write their own CEM rules for modded armor can also use the mod, as it avoids collisions with rules already in a pack.
How it compares
Resource Condition is a Fabric mod for 1.20.1, and it is not open source; under the Creative Commons Attribution Share Alike 4.0 license, it works on either side, and neither needs it. Skip Server Resource Packs is client-side only, open source under the GNU Lesser General Public License v3.0 only, and covers Fabric and Quilt for 1.19 – 1.21.10, so it addresses server resource packs rather than armor models.

What the author says
Stop 3D armor resource packs from breaking every modded armor. You install a 3D armor resource pack (CEM) and suddenly every modded armor looks destroyed — misplaced colors, dark patches, and holes you can see the player's skin through. Vanilla armor looks fine. Modded armor doesn't. All of it.
