UDK Lightmass Question

Zin83

I was wondering if you need an internet connection to run Lightmass in UDK. I don't have my PC connected to the internet and I get this error when I try to build lighting

"11:58:51 PM: [ERROR] Channel already registered, suggesting another SwarmAgent is running
11:58:51 PM: [ERROR] Sleeping for a few seconds and trying again"

I don't believe you need an internet connection. Does the lighting still build eventually despite the error? Swarm is the distributed computing system for Lightmass, but as far as I know Lightmass should still work even if you aren't connected.

No it hangs, and UDK ends up crashing

A few questions just out of interest that might speed up future responses:
What quality lighting are you trying to build?
What are you trying to light?
What results do you get building the lighting with lightmass turned off?
What are your computer specs?
