Hi all,

I know this questions has been asked so many times on this page. I’ve tried all sorts of things I could find online to solve the issue, but noe of them worked.  
I’ve tried:

-Set “EnableStandaloneMode” True on Swarm Agent

-Deleting the “saved” fille in the project file before re-opening the project

-Optimizing the lightmap resolution (all components looks green)

-Adding the SM\_Template\_Map\_Floor (I know this is random but I found it on reddit)

-Setting all the light source to “movable”

-Moving lightmass importance volume to a different position

-Uncheck “Affect Ray Tracing Global Illumination”

Any input would be appreciated. Thank you! 🙂
