Lighting Build Crashes Editor

BlueWake_1 · March 22, 2014, 8:50pm

I am having a big problem with baking my lighting. I am doing a test level and I have no issues with baking preview lighting but when I try and bake medium, high, or production it crashes. At first I thought it was my anti virus acting up so I disabled it but its still not working. I have also tried verifying my installation, did a completely new installation, and restarted my computer to no avail. Iv noticed my CPU shoots to 100% when building lighting but I would think that normal seeing as it could be a system hog. If anyone could shed some light on this I would really appreciate it. I’m at a complete loss here.

System Specs
Windows 8 64-bit
8gb ram
Intel i7 3.5Ghz
GTX 670

Here is the Error Log swarm gives me.

I have the same problem, It depends on the scene, but even with very modest scenes, lighting build fails if I set the quality in high or production. Medium works but takes quite a while. I guess this is a feature that will have a lot of updates ^^

BlueWake_1 · March 24, 2014, 5:34pm

I got mine to work on preview like you did but it only works with modest scenes. What system specs are you running? I am wondering if its a ram or CPU issue.

anonymous_user_b9532c9a · March 24, 2014, 6:13pm

Hi ,

Can you post your log file. it should be located in projectname\saved\logs (replace projectname with your project’s name).
Your crash callstack will also be helpful for us to further assist you.

Thank you and have a great day!

anonymous_user_6bb7d60a · March 24, 2014, 7:06pm

I’m actually pretty sure its more a RAM issue, my CPU is good, but I ‘only’ have 8Gb of RAM.

BlueWake_1 · March 26, 2014, 4:02am

Is there anything else you think I could try?

anonymous_user_6bb7d60a · March 26, 2014, 5:36am

Unreal Engine is installed on my SSD samsung pro 512 Gb (not partitioned), so it’s not a matter of drive, or partition.
Looks like it’s not a memory usage issue too… well ^^ I noticed that box reflection capture has an important risk of making the building process crash, I also noticed that by rebooting the engine, and building lights first, it has more chance to work.

So I managed to make it work on production quality on a very modest indoor scene I build myself from starter content assets, that’s how it looks :

I do not have a box reflection capture, just a lightmass, and I didn’t tweaked the lightmass, that may explain some visible artifacts around the white light lamp (static spot light). Well, I don’t want to go off topic too much but that’s how production quality looks on a housemade little scene with minimum tweaking

BlueWake_1 · March 26, 2014, 4:45pm

Deu_sex your issues are matching mine exactly. I got mine to work on production by restarting engine and then building. Only works with a modest scene not the unreal examples, it also dosnt work all of the time.

What anti virus are you running? I heard that Avast was blocking some users Swarm agent. I dont see how it could be anti virus because I disabled it on startup, but I figured I would ask in case I missed something. I am using AVG currently.

anonymous_user_6bb7d60a · March 26, 2014, 7:17pm

I only have microsoft security essentials and the firewall active, that’s all.

anonymous_user_b9532c9a · March 26, 2014, 11:45pm

Hi ,

We are still looking into this, please bear with us while we try to figure this lighting problem out. Thank you for your continued patience!

anonymous_user_42fa664f · March 30, 2014, 11:01pm

Hi,

For me the lightning buil doesn’t work if I have the Play mode On.

After pressing Play and getting warning message about build required I always tend to press Build. This causes errors almost always.

If quit Play the build process then ends successfully.

BlueWake_1 · March 31, 2014, 1:02am

Every time I build I have play off. I tested with play on and it failed like you mentioned.

anonymous_user_b9532c9a · April 17, 2014, 2:50pm

Hi everyone,

I am checking in to see if the most recent patch has helped your lighting build issues. Please let me know if there are still problems that need to be addressed. Thank you!

BlueWake_1 · April 20, 2014, 11:43pm

The new patch has not fixed my issue.

anonymous_user_b9532c9a · April 21, 2014, 1:47pm

Hi ,

Can you please post your dxdiag here so we can have a look at what may be going on? Thank you!

BlueWake_1 · April 22, 2014, 1:31am

link text

Here you go please let me know if you need any other info.

anonymous_user_b9532c9a · April 22, 2014, 1:19pm

Hi ,

Your dxdiag crashed and did not post the first portion of the information. It may be that you have a hardware issue that needs to be addressed. I would take your computer to be diagnosed and potentially fixed. Thank you and have a great day!

Lovecraft_K · October 31, 2014, 2:52pm

Hey -

I wanted to check in and see if in a current version of the Engine you are still experiencing this issue.

Thank You

BlueWake_1 · March 29, 2015, 8:13pm

I have recently been working with the Unreal Engine again and I am still experiencing the issue.

anonymous_user_6bb7d60a · March 30, 2015, 5:42pm

I recently upgraded my memory from 8 Gb to 16 Gb and since, I almost never crash ! This is a memory issue for sure, Elemental for example, can take sometimes between 10 an 12 Gb during the building process !!
