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:

PHP Code:

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.

lol this is going to help to avoid the annoying crashes whenever im testing models using stripper:source

[CosmicD]

This cured the crashes I had over the weekend in combination with another plugin due to one model not precaching (found that out with accellerator).

Using stripper to load the map diddn't help but this totally solved the crashes and now I see this in the error log:

L 04/12/2022 - 00:10:18: SourceMod error session started
L 04/12/2022 - 00:10:18: Info (map "l4d_hospital03_sewers") (file "/usr/local/games/l4d/left4dead/addons/sourcemod/logs/errors_20220412.log")
L 04/12/2022 - 00:10:18: [l4d_late_model_precacher.smx] UTIL_SetModel: Model models/props_unique/spawn_apartment/coffeeammo.mdl is not precached. Precaching late.
L 04/12/2022 - 00:11:01: Error log file session closed.

Lucky that the culprit remained with that one model

What about sounds? As far as I know I always have had a crash randomly when oxygen tanks are spawned. (At least I assume so.)

For me it always was "Late precache of PrecacheSound("physics/destruction/ExplosiveGasLeak.wav" that shows up.

https://github.com/ValveSoftware/Sou...es/issues/3413 This is the topic where I took the assumptions from.

Awesome!

The topic you linked is mostly related to the issue that this plugin addresses.

I've never experienced a crash related to unprecached sound files. When sound files are unprecached, they just don't play, or they are late-precached and play after an insignificant delay.

If you or anyone can provide an example of an unprecached/late-precached sound file causing a crash, then I can look into it.

Can this plugin replace such plugins?

You can use both. That plugin precaches specific files including sound files and melee weapon scripts. My plugin is just a failsafe for unprecached models that can crash servers.

OK, thanks

[Dragokas]

Neat idea! Thanks Crasher!
