For polygonal pots, this is the roundness of the polygon's corners. If this value is zero, the polygon has sharp corners. Positive values increase their roundness, up to one, which produces the circumscribed circle. Negative values also increase their roundness, but by shrinking instead of expanding the polygon, down to −1, which produces the inscribed circle. Values outside the range −1 to 1 are clamped. Note that this property has no effect unless Polygon Sides is at least two. This property combines with Polygon Bulge to determine the polygon's shape.
| Value | Description |
|---|---|
| −1 | Inscribed circle. |
| −1 < x < 0 | Corners get rounder as value decreases; polygon shrinks. |
| 0 | Sharp corners. |
| 0 < x < 1 | Corners get rounder as value increases; polygon expands. |
| 1 | Circumscribed circle. |
