Been trying all night but the new importer won't work, the command console closes and there is no imported data folder or geometry file.
Before it closes, the command console says "Data Stream was not empty" whatever the ♥♥♥♥ that means.

The ImportWizardLog.txt that appears in the importer's folder simply says:
"FR_CUSTOMDATA_PATH was not set as an environment variable !
Running RunLuaPreprocess.bat
Can't read script output file ( PreProcessOut.txt )"

Got no idea what's going on...
