So, I'm sure you noticed by now that Nadeo has rolled out ManiaPlanet 4.

It includes many awesome improvements, which I'm sure you're all digging into!

Lightmaps are now a new version.

This means all maps built prior to the release of ManiaPlanet 4 should be updated.

HOW DO I UPDATE MY MAP?
If it's your map, you can:
- Open the map in the editor.
- Save the map again (it will ask to recompute lightmaps - do it).
- Upload the updated map file to MX using the "Update" button at the top right of your map page.

WHAT IF I HAVE A LOT OF MAPS TO UPDATE?
If you run a server or just have a lot of your own maps to convert, you can use a batch command to mass convert a group of maps.

You can find guides on batch computing in this topic:
https://forum.maniaplanet.com/viewtopic.php?f=266&t=40871

If you convert a batch of maps using the batch command, the unique identifier (UID) of the map will remain the same as the original.

In that case we can run a script to update all of your maps on MX at once. Just send us a zip of the converted maps.

HOW DO I KNOW IF A MAP HAS BEEN UPDATED FOR MANIAPLANET 4?
Maps that have not been updated to ManiaPlanet 4 will display a warning at the top of the map page.

If you see no warning, the map has been updated (or is a new map built in ManiaPlanet 4).

You can search for updated maps by using this URL:
https://sm.mania-exchange.com/mapsearch2?gv=1

You can find maps that have not been updated yet by using this URL:
https://sm.mania-exchange.com/mapsearch2?gv=-1

WHO WILL UPDATE ALL THE MAPS ON MX?
The original author of a map. Ideally players should update their own maps.

However, there are many inactive authors.

The MX crew will coordinate an effort with a select group of trusted users to update all the maps on the site.

We will also gradually update large groups of maps from the start of MX. Our goal is to have nearly every map playable in the current version of the game.

If you find your map has already been updated by MX, you can check to make sure it works properly. If changes are needed, you can do them yourself and update the map again manually.

Hidden maps will not be updated by the MX crew.

Maps already updated to ManiaPlanet 4 will not be updated again by the MX crew.

Updating all the maps on MX to ManiaPlanet 4 will not happen overnight. It will take time.

WHAT ABOUT OLD VERSIONS OF MAPS?
We are keeping a backup of all the old versions of maps the MX crew updates.

We will not have backups of old versions of maps authors update themselves.
