Hey. Nice work! I'm looking into trying to get some old Enemy Territory maps into UE and this looks like what I need.
I tried the Not Fucking Dead (best name!) versions on 5.4.4 and 5.5.1 and they seem to mount. I enabled them but no settings appear. No Widget and also no HammUEr button on the toolbar. Can I force it somehow? The output log looks ok and says "mounted"
