I am pretty new to Unreal Engine, but haven’t ever encountered this problem prior to today. Every time I try to “Build Lighting” or “Build”, it initializes and immediately freezes. Watching my task manager, my CPU nor my memory increase at all after I try to build. It seems to freeze instantaneously. I was also having this problem in 4.15.2 and 4.15.3 today. I since updated to 4.16 and still receive the same problem. I have also tried clearing out Swarm’s cache, but the problem persists.
Yikes. Have you tried building a basic template project to see if it’s a general issue or just something in your project’s content? If not, can you and report back?
Thanks for the reply, I just tested this and still encounter the same problem. The main project isnt too much right now, so I was hoping that was the issue. I just have most of the gameplay mechanics done in the main project. Found this lovely error when i started to build the environment.
Ok, So how can I use this to correct the problem? I dont have any Crash Logs. I have some Build/Cook/Package Logs that were generated earlier today (not at the time of it freezing though).
We need to figure out what the problem is before we can fix it. Usually a hang is a thread lock situation but since it does hang, we need to get at the log file. AFAIK you can’t build anything in the editor and not produce a log so my only suggestion is look harder. And it’s not a crash log, it’s the log that the editor generates whenever it does anything (for the most part). It’s actually too chatty sometimes. Maybe the log you found is the right one. Just link to anything you can find and we’ll swim through it, but the link I gave does point to the right places for me.
I found the project log. These are the last few lines that reference to when I started to build the light. The log ends here.

Now we’re talking. So the editor talks to Swarm over a TCP socket. Something is stopping the connection. Not sure why it would hang, but whatever. If it’s safe, try disabling your firewall (and perhaps anti-virus) for long enough to build the lighting. See if that’s getting in the way.
So if i try to build only lighting, it gets to 100% starting up swarm. If i click build, it moves onto “Building Texture Streaming” and freezes at either 0% or 40%.
Swarm came up in my hidden icons tab the first (of 3) times. I meant to copy the files over for you but didnt get the chance. The only part that stuck out to me was that it simply failed to initialize.
To what part? The first two sentences are refering to inside the editor. The remainder is refering to the Swarm application, Ive never seen it load before today.
Anyway, here is the newest log for the project. link text
Did you try disabling the firewall? I can’t tell from what you said if that was the result of my suggestion or a reason why you didn’t take my suggestion.
Time to look and see if there’s (hopefully) any extra info in the logs.
