LODGenx64.exe failed to generate object LOD for one or more worlds

[nolbear]

Hello again, I'm trying to use DynDOLOD 3.00 (Alpha 14) to generate LOD for my game and I keep running into this error: "LODGenx64.exe failed to generate object LOD for one or more worlds." It seems to run into the error when trying to generate object LOD for the Tamriel worldspace. I've searched all over but can't find anyone else who has encountered this error. Any ideas what might be causing the problem? Here's a picture of the error message. Please let me know if you have any ideas. Thanks!

Hi 

I'm not sure that my PC is the problem as I am not getting any crashes just a failure to generate some of the lod, usually Tamriel Aut and Tamriel Sum but sometimes the other seasons when trying the test versions you've shared.  I also haven't changed anything with my hardware since I was able to successfully run DynDOLOD Alpha 182 when it was first publised. However I will still try to look into this as I appreciate something might have been changed by something in the background that I'm unaware of, thank you.

There might be changes to the load order that increased CPU, memory demand to higher levels than before and you were just lucky so far.

Other reasons might be OS update, drivers, loose cables, BIOS settings resetting to default, hardware going bad, cooling being affected because of dust (dead mouse not unheard of) etc. It is possible the issue is storage/disk related.

I understand thank you

I'll try to find out what I can.

Hi

Just in case this is of any value to know, I have just tried running the original Alpha 182 again having tried reducing my mod list a little incase it made any difference (I will be looking at the CPU testing tomorrow when I am less tired and can apply a fresher brain). I opened up task manager while it was running and at no point did CPU use go above 59% or memory above 66%. I was also checking to see if I had anything else running in the background at the same time which might have been interfering but there was nothing making active use of the CPU or Memory.

 

If I get any progress out of checking all the possible reasons on your list tomorrow I'll provide an update, just in case anything I find out proves helpful in any way.

 

Thanks again

Just a quick update whilst I'm still investigating things.

Stress testing CPU+RAM using OCCT Personal gives thousands of errors but testing just CPU gives none and testing just memory gives none. So now I'm trying to find out what to look at to understand these errors and solve any problems.

 

In the meantime could you clarify something for me? If I only have  "failed to generate object LOD for Tamriel SPR", so I use the Execute LODGen button on just the Tamriel (Seasons) worldspace, and it then manages to generate Tamriel SPR but fails on, say, Tamriel AUT, would the end result be that I had now got an Output folder with all the necessary object lod included or would the Execute LODGen process have undone any of the object lod generated in the original process? I guess I mean, does Execute LODGen just fill in the missing object lod so that if over several attempts I get a successful generation for each season I'd end up with everything I need?

Only select the worldspaces and seasons that failed before clicking Execute LODGen. You can repeat that as often as needed with different selections until it completed all world spaces successfully.
Do not Execute LODGen again for worldspaces and seasons that already completed successfully.

You can also copy/move already completed worldspaces and seasons *.BTO to whereever to make sure they are not accidently overwritten with incomplete generations that get interrupted.

IN the end you can merge all the *.BTOs that generated successfully into one complete output.

Ah thank you!  I'm not sure how I can seperate out the individual seasons for the Tamriel worldspace when Execute LODGen is used. The list of worldspaces just has one option for Tamriel (Seasons) so do I uncheck the seasons in the Seasons checklist that I don't want to repeat?

(Sorry if I'm asking ignorant questions :-/ )

You can select a single worldspace and select a single or more seasons and then Execute LODGen and wait for it to complete. Then select another worldspace and check different seasons and click Execute LODGen again.

LODGen produced 160 logs and I read through them, but this is all the info I have:

LODGen_SSE_SkuldafnWorld_log.txt (Skyrim.esm) says
"Error accessing D:\SteamLibrary\steamapps\common\Skyrim Special Edition\Data\Meshes\Terrain\SkuldafnWorld\SkuldafnWorld.4.48.-5.btr Unable to read beyond the end of the stream."

and LODGen_SSE_DLC2SolstheimWorld_log.txt  (Dragonborn.esm) says
"Error accessing D:\SteamLibrary\steamapps\common\Skyrim Special Edition\Data\Meshes\Terrain\DLC2SolstheimWorld\DLC2SolstheimWorld.4.-96.-8.btr Unable to read beyond the end of the stream."

In the meantime, I'm going to disable them in DynDOLOD and continue on.

Read the first post and/or https://dyndolod.info/Official-DynDOLOD-Support-Forum#Post-Logs which DynDOLOD log and debug log and which entire LODGen logs to upload when making posts.

 

Wasn't the original error and DynDOLOD log message like this:

25B -  Error accessing
There is a problem reading the mentioned *.NIF. ... If the mentioned file is a *.BTR terrain LOD mesh, generate a valid one with xLODGen and follow its instructions to always set a dedicated output folder outside of any game and mod manager folders.

If you followed the instructions of xLODGen to generate the files, it is possible something happened to them or something us interfering with reading them.
