Modulation curves are used to map values based on two axis.
- The dropdown menu determines the method of interpolating between the curve points.
Constant: Values stay constant until the next curve point is reached. This results in jumping values.
Linear: Values move linearly from one curve point to another. This is useful for getting very predictable results, but can result in robotic looking transitions.
Cosine: Flattens the curve around points, making the transitions smoother.
Cubic: Interpolates a smooth curve around the points. This is the best looking curve, but it can give unpredictable results as values in between points can go higher than the highest point and lower than the lowest point.
