If the material files (saved in sys-folder) should be corrupted somehow, you can always
- reset the materials from the pulldown menu (here areal standard is re-created)
- reload a saved material file, if ever saved
AREAL3D has also a built-in controll mechanism to avoid problems with corrupted files.
If a material file is corrupted somehow, it normally will be restored at start-up already.
Especially deleted material files will be restored.
