Would it be possible to compile a kit-bash like Halbert's U30C into one directory, instead of having dependencies spread out ?? (kuid-table modding ofcourse)
Yes, it's possible. Have a look at my Fowler tender in TRS2006, the coal rails are a mesh inside the tender folder. You can have as many meshes as you like and turn them on and off by editing the config file or under script control.
