Issue with Light build - swarm agent

Hi, I’m getting issues with lightbuild. It seems to freeze ue4 once i start the build process.

I think it’s something to do with my connection to swarm agent. I want to do it locally on this pc, i think i had a play with the swarm agent settings and it could of messed up maybe in an infinite loop trying to connect to it. The other problem it could be is my lightmass ini file, as i played with that, any ideas on how to reset these to default?

The reason for playing with these was to create more arch viz style lighting. But currently im at a loss as i cant even bake light… I’ve done a full reinstall as a last resort of my knowledge anyway :stuck_out_tongue:
