OpenTibia [Tool] OTClientV8 Offline Map Explorer - Browse Your OTBM Maps Without a Server

Warning: Project is still EXPERIMENTAL – expect bugs, freezes and occasional crashes. Some actions that normally wait for server packets will hang the client.

I've been working on a tool that lets you explore OT maps completely offline, and I wanted to share it with the community. This is a customized build of OTClientV8 designed specifically for OTBM map exploration - no server connection required.


What is it?

The OTClientV8 Offline Map Explorer is a standalone tool that loads your .otbm map files and lets you navigate through them just like in-game, but without needing a running server. Perfect for mappers, server owners who want to preview maps, or anyone needing to extract visual data from maps.

Quick demo:

Main Features​

• Full offline map loading (.otbm) straight from disk - no server needed
• Spawn Simulator – load your spawn.xml and see monsters appear in real-time
• Explorer Tools – change server light, outfit, speed, mount, addons, etc.
• Supports all client versions 7.40 → 12.20
• Hot-reloading – edit the map in RME, save it, and the client reloads it instantly

How to prepare data/things/[version] folder​

Example: data/things/1098

• Copy Tibia.spr + Tibia.dat from real Tibia client
• Copy items.otb (you can take it from RME)
• Put your .otbm map files here (you can have many)
• Put your spawn.xml / monster.xml files here (also supports many)
  
  

How to use
​

1. In “Enter Game” window change client version to the one you prepared (e.g. 1098)
2. On login screen click the new button “Offline Map Explorer”
3. Pick any .otbm file from your data/things/[version] folder
4. Enjoy!

Controls in explorer:

• Move → Arrow keys
• Change floor → Mouse wheel
• Zoom → Ctrl + Mouse wheel
• Teleport → Ctrl + Left Click on map/minimap

Spawn Simulator:
Open the panel → choose spawn.xml → watch monsters spawn exactly like on a real server




When you double click on a name, you can change its appearance. Its saved in data/spawn_data.json
Explorer Tools

Change global light, your outfit/mount/addons, walk speed, etc. – perfect for making cool screenshots or testing
Each setting is saved per map in data/explorer_state.json




Live map editing

Edit the .otbm in Remere’s Map Editor while the client is running → save → client auto-reloads the map in <1 second.

4. in "data" create folder called "things"
5. in "things" create folder for client version -> for example "800"
