The VSFACEHIGHLIGHT variable stores the reflex highlights of faces without materials to be displayed in the current viewport. The value can be in the range –100 to 100. The higher the value, the larger the highlight. The smaller the value, the smaller the highlight. If the VSMATERIALMODE system variable is on, attached materials ignore the highlight.
Note: An existing visual style is not changed when the system variable gets a new value. Temporary visual style will be created as a clone of visual style assigned for current viewport.
