Using latest Commercial builds from UE5 and C4D R26.
I can export out USDA groom files from UE5 from Ornatrix Plugin, and the .usda files do show in my chosen export folder.
But upon attempting to load them in from C4D's Ornatrix "Add Hair" folder select menu, the menu then lists no grooms as selectable, even though I can see them in the Windows Explorer window. So, it is almost as if the C4D importer cannot see them.
Thanks!
