UIBlock3D.CornerRadius

The Length configuration used to calculate a corner radius, applies to all eight corners of the body's front and back faces (XY planes).

Remarks

CornerRadius.Percent is relative to half the minimum dimension (X or Y) of CalculatedSize. Mathematically speaking:
float calculatedCornerRadius = CornerRadius.Percent * 0.5f * Mathf.Min(CalculatedSize.X.Value, CalculatedSize.Y.Value)

Declaration

public ref Length CornerRadius { get; }
