# Sorts the FBX files next to this script into TPF2 model editor folders.
# The model editor names the .mdl after the folder: <folder1>-<folder2>+<mdlname>.
# All LODs of one model go into one folder, so one import writes one .mdl:
#   1000_Holz_46E1_K_16m_lod0.fbx  ->  infrastructure-tracks+1000_Holz_46E1_K_16m\
