Build Lightning problem

Dear All,

Please help me about his issue, if i try to build just a light, the swarm can’t connect to the server.

Here is the log:

23:08:35: [ERROR] Channel already registered, suggesting another SwarmAgent or client is running.
23:08:35: [ERROR] If you feel this is in error, check your running process list for additional copies of
23:08:35: [ERROR] SwarmAgent or UnrealLightmass (or other client) and consider killing them.
23:08:35: [ERROR] Sleeping for a few seconds and trying again…

Please help me what can i do…

I am haveing trouble with UE4 lightmaps. I here it has something to do with the UV maps but I still dont understand.

Hey Drack,

This looks like it could get a little bit more traction on the answers forum for Unreal Engine. :slight_smile:

Are you trying to launch SwarmAgent manually for some reason?

Take a look at this thread to get more information about lightmaps -> :slight_smile:

@Drack What exactly happens when you build the light? (where do you see the upper error)?

When i click the Build->light only button, then a pop up window appear and freeze on 100%… I see a swarnagent icon on a system trey and they say to me the following errors:

23:08:35: [ERROR] Channel already registered, suggesting another SwarmAgent or client is running.

Guys i have a solution.
I read that swarmagent is use port 8008 to communication. I checked via cmd (netstat -p utp -t -p -b) and i realized that one of my remote management program is listening the 8008 port. After i uninstalled this program the agent is working very well…
So there is another question: Is there any way to force swarmagent to communicate another port?
