UDK "Can't Connect to Swarm

Rapture117

Hey guys,

I'm new to Polycount and hope I can get some assistance here since I couldn't get any on the UDK Epic forums. So, my problem is that every time I try to rebuild geometry,lighting, etc in UDK, I get this error that's in the thread title and it doesn't allow me to build lighting, geometry, or anything for that matter. So I ask you friends, what should I do?! I should also point out that I tried uninstalling/reinstalling and still got no luck & have Win. 7 64-bit with a 2.5 GHz PSU & an evga gtx 460. Thanks again guys!

Have you checked if it's being blocked by a firewall or anything? I know each time I run a new version of UDK for the first time, a window pops up asking me if I want to allow Swarm to have access.

Hey Sean,

I actually get that pop up every time but simply click "allow access" and it usually works. Never had any problems with my firewall settings, but I'll look into it!

why is there a second thread of this?

which version of UDK are you using? what quality of lights are you using?

Two threads :-O My apologies! Also, I'm using the newest August version. I've tried other versions and still get the same error.

i read up on it a bit and most people had this issue due to firewall or high quality lighting. if nothing comes of changing the firewall for it then try just using preview lighting

Alright, cool. Thanks man! I'll check that out when I get home (on vacation). I'm hoping to get it fixed so I can work on some maps on my off days when going to college. I appreciate the options though guys. Hopefully one of them work when I get home!

Alright, so I just got home today and tested out building in Preview Lighting and that works. However, when I try to build using Lightmass (which opens up Swarm) I get the "Cannot connect to Swarm" error & then the lighting build simply fails..

ok, this post may be old but if anyone was interested or was getting the same problem, i fixed this for me by launching SwarmAgent.exe first before starting up UDK

it can be found here "C:/UDK/UDK-2013-07/Binaries/SwarmAgent.exe"

1:46:24 PM: [Network] Coordinator has failed to respond
1:46:24 PM: [Network] Coordinator ping complete

i still cant connect to the coordinator, but i can now build the lighting.
i hope this has helped someone.
