Hi. I’m getting a curious error when trying to Build HLODs for a simple landscape. The logs show several ‘Assertion Failed’ errors referring to a file on D:… but I don’t have a D drive.
From what I see in the log, it looks like perhaps Fab.dll has a hard reference to D:\Build…
Has anyone seen issues such as this before?
Error from the log:
