# Rounded Polygon node
Generates a rounded polygon shape based on input UV at the size specified by inputs <b><i>width</i></b> and <b><i>height</i></b>. The polygon's amount of sides is determined by input <b><i>sides</i></b>. The radius of each corner is defined by input <b><i>roundnesss</i></b>. The generated shape can be offset or tiled by connecting a <b><i>[TilingAndOffset](/documentation/Nodes/UV/TilingAndOffset.md)</i></b> node. Note that in order to preserve the ability to offset the shape within the UV space the shape will not automatically repeat if tiled. To achieve a repeating rounded polygon effect first connect your <b><i>TilingAndOffset</i></b> output through a <b><i>Fract</i></b> node.
