Edit

The "Edit" option of the materials menu allows the user to edit the properties of already existing materials. When selected, this option will show the following tab to the user:

The user needs to select the material they want to edit in the "Select material to edit" dropdown menu. The user can modify the material color by clicking the small rectangle filled with the material color, as well as modify the Epsilon and Mu values. The meaning of these values is the same as in the "Add Material" tab, detailed in the previous section.

When the user has finished editing the parameters for the material, they need to click the "Save" button in order to confirm the changes.
