UE4 not responding during bake with "high" settings (.ini tweak)

I don’t know if it’s related, but did you perhaps deactivate texture streaming? I had a similar problem, reactivating it only in baking process solved my problem.

I don’t think it’s related, where’s that option besides in matinee? I had to increase the texture streaming pool size for matinee, but I’d say it’s irrelevant for the light baking, as I only touched those settings after “giving up” and doing a High quality bake for 3.5H.

So you are using a swarm coordinator to distribute the bake to other computers? What does it say in the log tab? (Double click the swarm agent icon in the system tray).
You can also try to ping the coordinator and the blades in the menu -> Network there. Check it in the log tab again.
When ever something weird happens it sometimes helps to clean out the cache. Go to Cache -> Clean.

Most likely it might just be too much data and too big light maps. I had it hanging when we just had too big light maps everywhere. Have you got any messages before the light build kicks off? See if there is something in the list that might stop it from baking. I personally never change the settings in the ini file and I don’t get bad results. Production is already a high setting so probably try to start a “Production bake” with normal ini settings and see how it looks.

In my projects I hardly ever set any light map higher than 1024. For furniture pieces probably never higher than 256. It’s more about the quality of the light map. If you have connected charts “around a corner” setting the light map to 4096 will not fix it. You need to fix the light map itself.

Finally another thought: Are you using 4.11? There was a bug where the editor would crash after building the lighting when you had a level hidden.

I’m sorry if I wasn’t clear about this. I’m using a single computer, the “coordinator” thing is just because of the message Swarm was displaying, because UE4 was not responding, I assume it’s its way of saying it doesn’t have instructions on how to finish the process apply the lightmaps and so on. I was using 4.12.5 and this week I’m doing the same with 4.13.

I forgot a bit about this post, but let me give you an update, I reverted the changes on the .ini file (default settings), the problem remains, AND it happened again when I simply left the computer idle during lunch time (it wasn’t baking or anything), and the same thing happened, UE4.exe was not responding (everything else was fine, autocad, photoshop, browser, etc.). I can’t know for sure that the problem is related to UE4. It happens when the computer stays idle, even with the proper energy settings, no sleeping mode, etc.

Right now I’m thinking about doing a clean OS install (inclined to windows 7) and hoping for the problem to go away.

Edit: I have 2x 2048 maps for the floor, those are the highest.

Edit 2: This post is no longer relevant as it doesn’t illustrate the problem I’m having correctly. The problem is “UE4 stops responding if the computer goes idle”.
