float ramp

 

Defines a curve that maps an input position (0..1 along the X axis) to an output float value (Y axis) — useful for shaping falloffs, weights, easing curves, and any value that should vary smoothly across a range.

Click on the curve line to insert a knot. Drag knots to shape the response, and drag the tangent handles for finer control over Bezier-type knots. Right-click a knot to change its interpolation (Corner, Smooth, Bezier) or delete it. Right-click the grid for reset, invert, copy/paste, and preset shapes.
