io_mesh_atomic, utility panel: extension of the option 'custom data file'
Changes - All properties of the Principled BSDF shader can now be set in the data file for each element. - Some important properties for Eevee are mentioned as well. Remember: a custom data file contains the size and material properties for each element. With this, the sizes and material properties of selected atoms in an atomic structure can be changed at once. The user can therefore store her/his own material properties inside this file and use it at any time for any atomic structures.
