The Number of field variables text field in the material editor allows you to specify the number of field variables to be referenced by a given material behavior. Columns for each field variable appear in the table in the data area of the editor.
To specify field variables:
Change the number of field variables in the Number of field variables box to the desired value using one of these methods:
Click the arrows to the right of the text field to increase or decrease the number of field variables.
Type the number directly in the text field.
Either method adds field variable columns to the table in the data area.
Enter the appropriate data in each cell of the table. You can enter data into the table using the keyboard. Alternatively, you can click mouse button 3 anywhere in the table to view a list of options for specifying tabular data. For detailed information on each option, see “Entering tabular data,” Section 3.2.7.)
