There seems to be a couple people who are unable to enable World Partition in the World Settings panel even though we can enable it in the Project Settings. Has anyone else encountered this and managed to fix it? Thanks. ---

I had the same issue. What worked for me was creating a new level in UE5 -AFTER- I had turned on World Partitioning in the project settings. The starter content maps didn’t work for me and didn’t give me the option of turning world partitioning on even if it was on in the project settings. Maybe that setting isn’t retroactively available after level creation? ---

You need to use the World Partition Convert commandlet. The steps are shown here: > **[World Partition](https://docs.unrealengine.com/5.0/en-US/WorldFeatures/WorldPartition/#worldpartitionconversioncommandlet)** > > An overview and how to for the World Partition system. ---

I’ve started on a blank map and the option was available, also if you close our map and open it again ue5 will give you the option to convert your map into world partition ---

That’s for existing landscapes though, not for starting new ones. Starting a new level after enabling it in Project Settings works. ---

But that’s the thing, there isn’t an existing landscape. Nothing has been done yet. I load Unreal. Make a new project. And that’s it. No new landscape or anything yet. ---
