If you are using a engine built from source, you can use the solution I came up with.
But if you are using a release version, here are the steps you can debug your web:
- Add
-cefdebug=portto commad line before you start your project.
Note: If your unreal engine version is 4.27.2, the default port is8088. And in version 5.3.1, there is no default port, so you must add commad line when you want to debug web.
- Create webwidget in your level
- Open Chrome(Edge), and open
chrome://inspect(if you use edge, openedge://inspect) - Add the
localhost:porttoDiscover network targets
- Wait for several seconds, you can find your web can be inspected.
