Overhaul lib is a Vintage Story mod by VSCustodian and Maltiez. Overhaul lib is a shared utility library for Combat Overhaul, Firearms, and other Vintage Story mods.

Why this mod is worth installing
This library is needed by mods that rely on its shared systems. It is mainly useful as a dependency rather than as a standalone gameplay addition.
What Overhaul lib adds
Overhaul lib provides reusable utilities for other mods, including Combat Overhaul and Firearms. Its purpose is to centralize common functions so dependent projects can use the same underlying tools.
The library records information about loaded mods, which can help connected systems identify the active mod environment. It also discovers and registers icons stored in the textures/sloticons folder for use by supported interfaces.
Another internal feature manages a cache for loaded shapes. Reusing these resources can give dependent mods a consistent way to handle model data without implementing the same cache logic separately.
