Hi everyone,
The given plugin is from this repo: https://github.com/AdamRichard21st/PackedModels
The only modification I made is that PM_SKIP_MAGIC was never called.

This plugin describes the following:

Features

Uses only a single .mdl file to render all weapons p_*.mdl and w_*.mdl.

Makes it able to reduce precache count by 58.

Disclaimer
Although this is a tool for rendering packed models in order to reduce the precache count, it does not unprecache the models by itself. Make sure to install an unprecache plugin that unprecaches all the p_*.mdl and w_*.mdl that fits better your server.

Based on that, I used the above code to unload the p_*.mdl and w_*.mdl.
My issue is that when I unload any of the w_*.mdl, the server crashes immediately on the first player spawn (likely because the model is missing).
How can I unload the w_*.mdl models properly, or what is a safe way of replacing them to reduce the number of actively loaded models?
(Only on the test server on Windows, prod is Linux, and the same thing happens there as well )

I have a crash dump as well, I can attach that if it's not an obvious solution from the provided info.

Thanks for your help in advance.[/CODE]

Hi, you also have this metamod plugin that do the job perfect, https://hlds.run/resources/32/ maybe combine with your plugin or this one https://hlds.run/resources/100/ but this one only removes weapons w_ models, not p_.

@yuyi,
I made a fix already, I'm not sure if all of it is needed, but it gets the job done.
The Ultimate Unprecacher can't be used on the Windows test server out of the box, and I haven't touched Metamod in VS in a long time, so I didn't try to build it for Windows.
On the other hand, this "World Model Group" is new for me and looks promising, it has a few more models packed into it than the one I use. I'll combine the two to maximize the number of unloaded models. Thanks for helping out, it helped me one way or another!
