Hello Mulldoon,

You might need to rebuild UnrealLightmass.cpp within VS under the development editor target. I would also be sure you have added a ‘Lightmass Importance Volume’ around your scene so it can initialize and build effectively.

I would also take a look at the Swarm Agent Troubleshooting Guide on the Epic Wiki to see if the suggestions there can help resolve your issue.

Let me know if you have further questions.

Thank you,

Rebuilt the lightmas tool, its now working.
Cheers

Rebuilding UnrealLightmass.cpp worked for me. Thanks.

THIS WORKED FOR ME:

If you’re using 4.10 or later you will need to have the VS2015 dependencies installed.
You can download the Visual Studio Dependencies from Microsoft’s website:

VS2013: http://www.microsoft.com/en-us/download/details.aspx?id=40784
VS2015: Download Visual C++ Redistributable for Visual Studio 2015 from Official Microsoft Download Center

I tried to follow, but I found that there is No Swarm Agent for Linux, or I don’t know how to launch a GUI for it
