It seems that World Partition affects landscape and foliage differently. Is that correct?

Hi, I’m new to Unreal Engine. I created a relatively large world using World Partition, with a landscape and some foliage placed on it. In the editor viewport everything looks fine, but when I launch the project in PIE, World Partition seems to behave differently for the landscape and the foliage. In the screenshot below you can see that the foliage is already visible, while the landscape underneath hasn’t been rendered yet. Could anyone please tell me how I can fix this?

Thank you for your help!

Hello there @MishOvch!

Welcome to UE! And yeah, it is possible that WP treats landscape and foliage in different ways, depending of your setup. We just need to make sure that both are streaming the same way.

First of all, in your map, go to Window > World Partition > World Partition Editor. There, check if your Foliage Actors are set to “Persistent Level”. If this is the case, then the foliage will be loaded all the time, while the lanscape waits for its cell to be activated.

To solve the problem, right click on your foliage, select “Convert to Foliage Actor”, and save it to your WP cell, instead of the persistent level. Apply this to all affected foliage, and you should be good to go.

And if you still encounter any delays in loading, you can play around with the streaming distance value under Project settings. Also, since you are getting started with UE, I would suggest checking out the community’s documentation on the matter, specially the world bulding guide:
