I don’t know is it a bug for preview version but i have build problem. I have interior/exterior architectural visulation scene and it has foliage. I can build it at UE4-10 but i haven’t built it in UE4-11 preview2 and preview3.

First of all, i cloned my scene by using Launcher Library. Then i convert it with 4-11 preview. After that when i try to build it, a message appears that world settings map error.

Then swarm kicked me off and building operation failed. When i try an empty scene build operation is working well.
Is it a bug for preview version? How can i build it with 4-10 and can’t build with 4-11?

This is the scene:

Hi ,

The “Maps need lighting rebuilt” warning is already logged in our system with UE-24112.

As far as Swarm Agent failing to kick off there could be a few reasons for this specifically, but I’ve not yet experienced anything like this with the preview releases.

If you have any issues with Swarm Agent I would recommend checking out a troubleshooting and tips guide I posted on the Wiki a while back. I’ve linked to the part about “Swarm Failing to Kick Off” as this can help troubleshoot some of the common reasons this would happen.

If the issue returns and you’re unable to find a solution in the troubleshooting guide please post back here with any additional details.

Thank you!
