Swarm Failing

jsargent

Hi guys...I just installed UE4 and swarm is failing. I had this problem with UDK before and it just started happening suddenly in any version of unreal I used. It did used to work a long time ago, no idea what changed I tried reinstalling, tried disabling all firewalls, tried setting to high priority in task manager... Basically I tried everything I could find after extensive reinstalling and researching the issue. The old swarm used to crash the editor but in UE4 it just fails without a crash. I would really appreciate any help, I'm totally out of ideas.

Thanks guys

I don't know, but, make sure your light map sizes are all correct, and you have clean lightmap UVs that aren't too packed.
One time I had swarm failure, I accidentally set the light map for a static mesh to 6432 (should have been to 64 from 32)
Then, this other time I had much too complicated meshes (lots of floating geometry) and it would crash lightmass.

It wont even light the default scene with preview settings. In fact it even crashes if I just try to open it without unreal even open Anyone got any other ideas, I'm on the verge of reformatting everything

This is whats in the log...

also I can open the swarm coordinator but if I try to open the swarm agent it just comes up in the task bar briefly and then disappears. This meant I cant get in to change any settings.

I had problems before with Lightmass, which I believe that Swarm is, and the problem was the my firewall, which blocked communication with the 'server' that swarm create. Maybe take a look at that.

thanks for your reply but I have already tried disabling both firewalls and I have tried unplugging the internet too

Did you try disabling your antivirus? Avast's file shield will cause this issue if Swarm isn't on the exception list

Are you trying to use swarm to distribute your lighting builds between multiple machines, or can you not bake lighting at all (on a single machine)?

I had do jump through some hoops and download some "patched" files for swarm from the UE4 forums to get distributed bakes working correctly. If that's your issue, I can dig up that stuff when I get home.
