Parameters

Polygon Settings

  • Seed
    The Seed used in the layer.


  • Spline Smoothness
    Controls the number of steps for each spline, with a higher count producing a smoother and more rounded shape.


  • Surface Smoothness
    Rounds the curvature of the shape.


  • Corner Offset
    Rounds and shifts the shape outwards.

Outside Settings

  • Height Offset
    Shifts the height of the polygon.


  • Outer Falloff
    Controls the outward falloff of the polygon.


  • Falloff Curve
    Adjusts the steepness of the outer falloff.


  • Noise Strength
    Adds noise into the outer falloff.


  • Noise Scale
    The scale of the added noise.


Inside Settings

  • Height Offset
    Shifts the height of the inner influence area of the polygon. 


  • Inside Falloff
    Controls the inward falloff of the polygon. 


  • Falloff Curve
    Adjusts the steepness of the inner falloff. 


  • Noise Strength
    Adds noise into the inner falloff. 


  • Noise Scale
    The scale of the added noise.
