How to Fix Logical Zoom Not Working When You Press C
Check for a Keybind Conflict First
The most common reason zoom does nothing is that another action already owns the C key. Open Options → Controls → Key Binds and search the list for any entry bound to C (a very frequent culprit is a "Save Tool" or similar inventory action). Either clear that binding or move it elsewhere, then confirm that Toggle Zoom (or the zoom keybind) is still set to C.
Reassign the Zoom Key
If you would rather keep your existing C binding, change zoom instead:
1. Go to Options → Controls → Key Binds.
2. Find the Logical Zoom entry (it may appear as Toggle Zoom).
3. Click it and press a new key that is not already in use.
4. Save and return to the game.
Test It In-World
Hold or press your chosen key while looking at a distant object. If the view still does not change, leave the world and re-enter so the keybind reloads, then try again. Remember the mod distinguishes a *toggle* behaviour, so a single press may switch zoom on and a second press switches it off — if you expected hold-to-zoom, that is why it feels broken. Once the key is free of conflicts, zoom works reliably.
