Hi,
We have managed to take our OBJ files and process them into VEF format with all the LODs and manifest files.
We have also managed to successfully convert from VEF to VTS tiles and create tilesets for small areas.
Below is a smaller dataset of 36 tiles up and running.

Our problem is that when I scale up and put a lot of tiles in I am getting random Core dumps (Segmentation fault (core dumped)) and I have no idea how to troubleshoot. If it failed on the same tile every time I could go back and reprocess that one and it would be fine.
All websearches point to the Segmentation faults being connected to memory and write permissions. We are running this on a VM online rather than a physical machine. it is a 32 core 96gb instance.
I don't think it is the 3d models or the manifest - but perhaps I have overlooked something.
Do let me know if there is anything you think we may have missed and I would be very grateful for your assistance - I feel like we are very close indeed to getting this up and running!
Core dump1.txt
Core dump2.txt
Core dump 3.txt
core dump 4.txt
manifestjson.txt
renamed to .txt instead of .json because json uploads are not supported on github
I have also sent this report to info@melown.com if you would like a more in depth conversation.
EDIT: SOLVED!
Turned out that it was an obj file missing. We found out which one by running on a single core instance and it dumped at the same tile every time. It would be super to have a better set of error messages when things fail ;)
