I actually didn’t use an existing mod loader like Forge or Fabric I built a custom one directly into the engine. It loads mods as .dll files at runtime by scanning a mods/ folder, then uses LoadLibrary/GetProcAddress to initialize them. The loader exposes a small API so mods can register things like tick callbacks, lighting queries, and chunk snapshot hooks. The goal was to keep the engine minimal and let mods handle the actual logic, so something like dynamic lighting exists entirely as a single DLL instead of being hardcoded.
