Build Light function hang up EDK

[Plastik]

Level size: 4096х4096х32 with few walls and sky light added. When i`m pressing «Build Light» with following options:

- Build BSP
- Build Static Meshes
- Build Only Current Level
- Preview Quality
- Use Lightmass

And when i`m pressing OK all i can see is just Building map and (Collecting the scene) and Swarm Agent. Thats all. Nothing happen and UDK hang up (even CPU load = 0).

It works fot me only one time (when i`m first time start UDK).

Specs:

E6750 / 4Gb / 8800GTS 320 / XP SP 2.0

PS. Without Use Lightmass option it works.

[maj86]

I have this same problem with a very small map and a few lights. It works fine when the Use Lightmass option is unchecked.

[WOBBLER]

The lightmass client is a 64 bit application can that be the problem? I dual boot and when I use xp 32bit I get the same problem but using xp 64 it works fine. Edit, Now its happening with xp64, here is the error log

I had the same issue's. Unchecking Use Lightmass solves it. If anybody has a solution for this it would be awesome! Really would like to work with te lightmass system.

I'm running on Vista Ultimate x64

[HEGI]

This could be an issue with your firewall, i have Zonealarm asking me about lightmass each time the swarm agent starts.
Windows firewall is no different i think and restricts access.

[VorLoN]

Did you guys place a ightmass importance volume?

[G0DLIKE]

I have Win32 (but running on Athlon 64) and no problem for me.

[Wildstyle]

I've disabled my firewall and virus scanner wich mde no difference in my case. I think it's related to the swarm agent, wich gave me a the message:

Fialed to initialize SwarmCoordinator. And the "Building Map'" dialog hangs at "Collecting the scene".

After trying this i've added the lightmassInmportance volume, now Swarm agent gives no errors but "Buidling Map.."" still hangs at collecting the scene.

[G0DLIKE]

Do you have enough space on hard disk?
Is your scene LARGE?
I had this same effect when trying to work it out with a large skysphere.

[Wildstyle]

I just subtracted a cube 1024x1024x256 and slammed some textures on there, there a basic pointlight in the centre nothing fancy. There's enough free space in my HD.

Also under the "swarm status" tab it doesn't show any tasks in progress

[WOBBLER]

After using a lightmass importance volume my problem seems to have gone, thanks VorLoN.

[Wildstyle]

I'm still havng the problem,i've been messing with my firewall, running as admin, de-installin and re-installing. Right now I'm using the example-map as the try-out for re-doing the bake. I've mae no changes on it so the lightmass Importancevolume is also still in place.

In the logfiles from the swarm agent it keeps displayig the same massage:

[PingCoordinator] Coordinator ping failed
[PingCoordinator] Determined that we couldn't ping the coordinator
[PingCoordinator] Coordinator ping failed
[PingCoordinator] Determined that we couldn't ping the coordinator

I'm completely out of ideas

[skasteve]

Wildstyle -

Can you follow this repro and send me what is displayed in your Swarm Agent Log tab:

1. Load ExampleMap
2. Build Lighting using preview lightmass

Also view the Swarm Status tab and see if your machine is listed there.

[Wildstyle]

Hi Skasteve,

thnx for the repy. In the log Swarm Agent log tab is says the following:

23:29:27: Starting up SwarmAgent ...
23:29:27: ... registering SwarmAgent with remoting service
23:29:27: ... registering SwarmAgent network channels
23:29:28: ... initializing SwarmAgent

23:29:36: ......... SwarmCoordinator failed to be initialized
23:29:36: ...... initializing local performance monitoring subsystem
23:29:38: ... initialization successful, SwarmAgent now running

In the Swarm Status tab, no machines are listed at all.
I hope this helps

[Argawaen]

Anything here any help? http://udn.epicgames.com/Three/SwarmDevelopmentAndSetup.html

Cheers
John

[sgt_goomba]

FYI, I have this same exact issue. Found this thread via google. I have windows vista 64bit. Guy next to me with same exact setup can build all with lightmass just fine. I only tried a simple box room with one point light. Nothing in the above link seems to help me.

[Sannaakita]

hi

I have very similar problems.
I couldn't run lightmass at all without it crashing - I've fixed most problems by changing changing the swarm agent and coordinators run preferences so that they run in xp service pack 2 compatability mode, turning off desktop themes (I'm running vista and that setting seems to always give problems)and that I'm running them as administrator.
However I still get the error dialogue 'The lighting build failed' though there seems to be no clue as to why in the log file. (see below).

I am running 32 bit vista - is this the problem? if not any ideas?

thanks

[Sannaakita]

I should add that the swarm status just seems to continue for ever in an 'importing results' state. Whenever the bar fills up - it just extends a little more.

[Sannaakita]

Ok I changed the swarmagent settings to enable standalone mode.
I no longer get the failure error message box. Instead the status never gets beyond processing mapping, and the log file now shows:

any ideas or suggestions?

I don't think I have the same error as Sannaakita. When I build all, it freezes at "collecting scene" and I get no error message.

[Sannaakita]

I stopped using lightmass for a while - but strangely my problem has gone away - the only change I can think that might have fixed it was that I added a player start!

I wasn't too worried before as all I was doing was playing with the lighting and not walking around the level - but its the only actor I've added and I'd stopped fiddling with the settings so i can't think of anything else.

[Sannaakita]

The only other thing I did - now come to think of it - was to go through every .exe file in the binaries and make sure that it was 'run as administrator'. It may be changing one of those that did it - but since I changed them all I couldn't say which.

[Sam2]

I am getting similar errors, the editor launches the SwarmAgent executable, but then the editor hangs on "Collecting the Scene". The SwarmAgent has no activity, it just sits there idling. It manages to connect to the SwarmCoordinator just fine, both locally or on the network. I've tried changing compatibility modes of the associated executables in the Binary, Win32 and Win64 directories. Here are the specs on my desktop:

Intel Q6600
BFG GeForce8800GTX OC2 (x1)
XFX 780i motherboard
8GB OCZ Reaper HCP RAM (4x2GB)
Windows Vista Home Premium x64
plenty of HDD space, 800W PSU, etc...

Everything is also installed into the default directories.

However, lightmass works fine on my other crappy little computer... here are its specs:

AMD Athlon 4400+ X2
BFG GeForce 6600GT OC
Asus A8N-E Motherboard
1GB Corsair something-or-other RAM (2x512MB)
Windows XP Professional x32
plenty of HDD space, 500W PSU, etc...

OS maybe? My friend has no problems on his 64-bit Windows Vista system...

[flyinrooster]

I get the same issue as the above poster, only my SwarmAgent can no longer initialize the SwarmCoordinator. Funny thing is, this was working for a while, then suddenly stopped. I've tried a lot of troubleshooting myself, but nothing so far has worked.

[sandiegojoe]

It looks like this problem is related to "swarmagent.exe." The editor uses this app to share the processing of the lighting among other workstations on your network. (It's located in the "Binaries" folder of the UDK install) If I try to open swarmagent.exe directly by clicking the executable, it immediately crashes with the following ".NET Runtime 2.0 Error" in the event log:

EventType clr20r3, P1 swarmagent.exe, P2 1.3.518.0, P3 4ae724c1, P4 system.drawing, P5 2.0.0.0, P6 471ebf30, P7 7da, P8 31, P9 system.argumentexception, P10 NIL.

I've repaired, removed and reinstalled every .NET version I have. (Starting with 2.0, and eventually moving on to all the others after that didn't work.)

Interestingly, I get the exact same error when I try to run a DVD ripping utility called "Handbrake." This all seems to be related to something with the .NET 2.0 framework, but I cannot figure out what exactly. Also, you will notice the error contains a reference to a function called "System.drawing." This also appears when I get the error in Handbrake. Does anyone out there know how or why this function might cause a problem?

Hi,

I was facing the same issue with Vista 64: Swarm Coordinator launching and Udk going blank when using lightmass.

I've found a workaround that worked for me, I've deactivated Vista firewall, restarted my computer, when back on the desktop closed Kaspersky, launched UDK then loaded the example map, finally I've clicked on build lighting ( with lightmass on ).

Now swarm coordinator launch and my computer is listed, UDK doesn't hang up anymore, but...

Now, whenever i try to build with lightmass, Udk show me a nice message :
" Failed to build lightmaps. Please read the log file. "

And then another one:
" Lightmaps need to be rebuilt."

I've tried to replace Binaries\Win32\UnrealLightmass.exe with the one in Binaries\Win64\
I've messed with the light in the level and tweaked the configuration...No luck.

Is there something wrong with ExampleMap.udk, something misconfigured ?

[Plastik]

Tip from me:

Try to use DominantDirectionalLight (dont forget about Lightmass options) and also build Lightmass Importance Volume around visible part of your level. And if you did everything right, after light rebuilding you`ll get this:

:p

PS. If your level is huge and with alot of static meshes, light rebuilding can take few hours :D

Lightmass @ Work

:cool:

[Sam2]

The issues are not with the map but with the system's configuration most likely. As I mentioned, my other computer runs lightmass just fine on the included and on custom maps. That other computer is also a fairly fresh install.

I really can't seem to narrow it down. Doesn't appear to be caused by 64/32 bit, videocard brand, cpu brand... hmm. Keep trying I guess.

Maybe its because of Vista? I`m using XP.

[Jmc]

Already tried that, I've created a small room with a small LightMass importance and put only one DominantDirectionalLight, it doesn't work neither.

As if swarm coordinator starts and then can't launch Unreal lightmass.

I'll try with a fresh install of UDK ans see what happens.

[Sam2]

Maybe its because of Vista? I`m using XP.

I tried on a classmate's Vista x64 laptop and lightmass worked fine. Everyone else I've talked to though who's had it working is on XP.

I just tried upgrading to SP2 (thought I did) and that didn't help at all. Tried turning the UAC settings to ON to see if that did anything but nope, tried playing with the Windows themes too...

[morpheus2010]

I found the light system of udk has a lot of problem.

the shader can't show all right,even I turn to set the light properties,there is only white ..

I can't see the words I saw there,have you met it?



I'm using xp sp3 ,in ati display with wrong shader showing.

my classmate's XP SP3,with GTX275 is all right show the shader.

[Sam2]

I'm not too sure what you mean, but look along the top of the view port and make sure you are set to view in "Lit" mode, not "Lighting Only".

[morpheus2010]

If there are two or more mesh ,the shader show just like your display card go wrong like too hot in game.

the shader flash ,it disapear and show again.

so I have to use Nvidia' display card.

---------------------------------------------

today I found when I turn to the light properties,means press F4.

the words like light component,and words like lightmass all gone.

there are white colour only .

I have to close UDK and open again,now it can be see.

[morpheus2010]

I'm not too sure what you mean, but look along the top of the view port and make sure you are set to view in "Lit" mode, not "Lighting Only".

in the two mode，the shader show all wrong.

when I try the UE3 FOR GOW,It works all right.

[Plastik]

You can try this: Load ExampleMap.udk and than press Build Lighting (Use Lightmass) and see what happen next.

[Jmc]

After a fresh installation of the UDK turning off Kaspersky, UAC and Vista's firewall, Lightmass and swarm agent are finally working like it should be.

The other thing I did was to change the install path from c:\UDK\UDK 2009-11-3 to c:\UDK.

[morpheus2010]

You can try this: Load ExampleMap.udk and than press Build Lighting (Use Lightmass) and see what happen next.

thank you,when there is only one object,the shader show all right.

when you build another,the shader of them show all wrong

I'm sure a old ATI video card has the problem with it is normal.

a same map on the Nvidia's machine don't show the wrong shader.

what problem I meet before rebuild light.this is only small wrong showing.

what you have talking about I would meet not long.

I'm a new guy for UDK.thanks a lot.

yes,when I rebuild light, my firewall show it has let it go.

they need to check the set of firewall.

thanks a lot!
I‘m a freshmen eve didn't know the rebuilding function.

some sitiuations,there is no shaders if I didn't use light mass.

oh! I found out!

when I input a light mesh,but what ever I set it properties,like cast shader.

It show no shader at all. I have to rebuild and set as you said.use light mass.

thanks!!

I shuould learn it myself haldly.

[morpheus2010]

the rebuiding program will creat it self everytime,and its name always change.

when I use XP,the firewall of systerm didn't show anything and let it go.

my other firewall.show all that happen.

[georaldc]

I use windows 7 firewall control, and everytime I build lights, it goes off warning me whether to allow UnrealLightmass or not. If I block it, the building process just continues and doesn't end. Allowing it allows the process to complete with no problems. What's odd is that it will always asks for me to do this every single time I build lights, so I have to set firewall control to allow everything while I use the UDK.

[qwertyuiop]

hmm i have windows 7 and it was running fine with lightmass for a while actually,
then one day i try to build the lighting with lightmass and it stops with a "critical error" and stops the swarm agent... i never had any problems with firewalls and i haven't messed with any of the binaries and programing... any ideas?


ps it works with lightmass for example map but not for my map...

[TheAgent]

this is 9- 10 month old thread

[qwertyuiop]

yeah i no but the same problem popped up... any ideas?

i am trying to install the newest update and see if it will help...

[qwertyuiop]

ok so i installed the august version and tried to build lighting with the same results: builds on example map, not on mine, and it works without lightmass... Help Please!!!

[xxxhackaxxx]

Okay so i figured it out!!! (Well at least for myself)
Under your Firewall or any type of security software make sure the following are set to allowed

C:\UDK\UDK-20xx-xx\Binaries\SwarmAgent
C:\UDK\UDK-20xx-xx\Binaries\SwarmCoordinator
C:\UDK\UDK-20xx-xx\Binaries\UDK

(these are not the .exe XML Configuration Files, they are the Applications)
also make sure you set them to run as administrator.
Good luck!!!

I have the hanging problem too, what i do is kill udk when it hangs through task manager but leave swarm open, then i reopen the project file and rebuild and it works.
