Hey there Antoine,
I’d think that this is likely related to code existing outside of the root. VFS could probably address this, but I’m not confident. Do you happen to have some of your patches to the engine handy for me to review?
A couple of related, but minor questions:
- Can you provide your BuildCofniguration.xml and command line?
- Can you provide the initiating machines UBT log?
- Does this work without caching?
Kind regards,
Julian
