I made several effects but they has two types of icon. Could anyone tell the difference between them?

The β€œSun” Icon indicates that the shadow is β€œmostly” uniform all the way around the object. The line under the circle indicates that the shadow style casts a shadow toward the bottom of the object. This is a quick visual indicator of which ways your shadows cast in figma. Adjust the X/Y values of the shadow styles and the lines will change to indicate which side of the object the shadow is predominantly cast.


Super Thanks!
And I realized that the icon will be changed as I register to a style library.
