Splitting Single OBB Expansion file, into Multiple OBB Expansion files [Unreal Engine 4]
Since OBB files have a limit of 4GB, we are looking at providing multiple OBB expansion files.
On this topic, I was reading the following page
https://developer.oculus.com/documentation/unreal/ps-assets/
I see how additional OBB expansion files can be provided as required assets, but how can the initial OBB be split into multiple smaller files?
Does this require Engine changes? Just wondering if any other Unreal Engine developers have encountered this issue, and how they have solved it?
Thanks

Does anyone have any idea know how this can be achieved?
I have seen this done for other Oculus Quest titles, that are using UE4.
Any help would be appreciated.Bump. I'm also interested in getting this working.
Bump. Would also like to find the answer to this. 🙂
Actually, enabling Allow patch OBB files and Allow overflow OBB files in Project Settings is what solved the issue I was having.
OP, if you want the 'initial OBB be split into multiple smaller files', then I suppose additionally you could disable Allow large OBB files, or even enable Force small OBB files for a 1gb limit. Can't think of a reason one would need it put a cap on it though.
Reading this documentation actually helped me understand this topic a little better: https://docs.unrealengine.com/4.26/en-US/SharingAndReleasing/Patching/GeneralPatching/CookingAndChunking/
were you able to split obb files or this was just an assumption? thanks in advance!
Hello,
I too am trying to find a way to get more then one OBB file. My game is larger then 4g and I can’t figure it out. Do I have to create PAK files? I’ve tried the settings you suggested above but I still got the error during packaging saying I’ve exceeded the 4g limit.🙏🙏🙏
