Which MinMaxCurve type is the cheapest to use?

The MinMaxCurve type known as "Constant" is the most efficient option to use in terms of performance. A Constant MinMaxCurve simply holds a single value, meaning it doesn't need to perform any calculations or interpolations to determine the output. This makes it very lightweight in terms of resource usage and processing time.

In contrast, the other choices involve more complex operations. For instance, a Random between two constants requires the system to generate random values each time it is evaluated, introducing additional computational overhead. The Smoothstep type involves mathematical calculations to create a smooth transition between values, thus requiring more processing power. Finally, using a Curve involves evaluating a more complex mathematical function, which can be computationally intensive, particularly with many points defined on the curve.

Overall, the Constant MinMaxCurve stands out as the most optimal option when performance efficiency is a priority, as it directly provides a singular, predictable value without any additional processing needs.
