SDF for a 2D star shape.

Parameters

Name	Description	Regular Handling	Read-Only Handling
Radius	The distance from the center to each outer point on the star.	Runtime	Baked
Points	The number of points for the star. When this is a non-integer value there will be one point that is partially cut off at the bottom.	Runtime	Baked
Tightness	How much the inner points of the start are pulled towards the center. At zero this will produce a polygon with two sides for each point. At one it will produce thin lines radiating from the center.	Runtime	Baked
UV Mode		Semi-Baked	Semi-Baked
None: Cartesian: Polar:
