About

Catches unprecached models and tries to precache them to prevent crashes.

This plugin addresses the rare occurrence of a well-known UTIL_SetModel crash that has existed for as long as both L4D games have been around. The crash can occur even on completely vanilla servers, but can occur more frequently on modded servers that run plugins utilizing models.

If a model cannot be precached, this plugin will block UTIL_SetModel and the entity will (probably) just be invisible or be a giant ERROR sign.

Disclaimer: This plugin only helps prevent crashes related to unprecached models (UTIL_SetModel crashes). If this plugin is detecting a lot of unprecached models on your server on a regular basis, there may be severe underlying issues with your server that need to be addressed.

Do not use this plugin as a "global precacher" for models. When a model is late-precached, players will experience a stutter (more obvious on low-end computers), so it's best to make sure that plugins utilizing models properly precache them inside OnMapStart().

Example:

L 04/11/2022 - 13:15:48: SourceMod error session started
L 04/11/2022 - 13:15:48: Info (map "l4d_hospital03_sewers") (file "C:\l4d1ds\left4dead\addons\sourcemod\logs\errors_20220411.log")
L 04/11/2022 - 13:15:48: [l4d_late_model_precacher.smx] UTIL_SetModel: Model models/props_unique/spawn_apartment/coffeeammo.mdl is not precached. Precaching late.
