Using Mapping Tools in osu! lazer

osu! lazer has a different beatmap editing workflow from osu! stable. Mapping Tools can edit beatmap files from either client. In lazer, use its external editing workflow and be aware that some features have limitations.

How to use Mapping Tools in osu! lazer​

In the osu! lazer editor, click File > Edit externally. This will create a temporary folder with all the files of the beatmap set you are currently editing. Mapping Tools will automatically detect this folder and set it as the selected beatmap. Once you're done editing with Mapping Tools you can click Finish editing and import changes and osu! lazer will import the changes.

File > Edit externally

Heads up about continued lazer compatibility​

As osu! lazer is actively in development, it's file format and client are likely to change and that can cause Mapping Tools to break. If you run into any issues using Mapping Tools on lazer that is not on this list, report an issue with About > Report an issue.
