> If a player attempts to join and is immediately met with the error: **"Server is enforcing consistency for this file: models/infected/..."**, it means the server's security settings are preventing them from using custom weapon skins, character models, or texture mods.

## 1. The Global Fix

To allow all players to join regardless of their locally installed Workshop mods, add this line to your `server.cfg`:

```cfg theme={null}
sv_consistency 0
```

***

## 2. Understanding the Modes

* **`sv_consistency 0` (Recommended):** Disables the check. This is standard for casual and public servers, as almost all modern L4D2 players use at least one cosmetic mod.
* **`sv_consistency 1` (Competitive):** Enforces a strict match between the server and the client. This is used in competitive play to prevent players from using "Cheat" mods, such as neon-colored zombies or transparent wall textures.

***

<Important>
  ### The Participation Penalty

  Enforcing consistency (`1`) on a public server will typically result in **40-60%** of potential players being kicked instantly. Unless you are running a strictly vanilla or tournament-style lobby, we recommend keeping this value at `0`.
