MIX (math/mix/float)

The MIX node performs a linear interpolation between two float values based on a third float value. It allows you to smoothly blend between two numbers by specifying a mix factor.

​
Inputs

  1. a (float, default: 0): The first value to interpolate between.
  2. b (float, default: 0): The second value to interpolate between.
  3. c (float, default: 0): The mix factor that determines the interpolation amount. A value of 0 returns a, a value of 1 returns b, and values in between return a linear blend of a and b.

​
Outputs

  1. result (float): The interpolated value between a and b based on the mix factor c.

​
Configuration

This node has no additional configuration options.

​
Usage

To use the MIX node:
  1. Connect the first value you want to interpolate between to the a input.
  2. Connect the second value you want to interpolate between to the b input.
  3. Connect a value between 0 and 1 to the c input to control the interpolation amount.
  4. The interpolated result will be available at the result output.

​
Example

Here’s an example of how you might use the MIX node in a spell: 
input1 [Slider] (min: 0, max: 100, default: 25)
input2 [Slider] (min: 0, max: 100, default: 75) 
mixFactor [Slider] (min: 0, max: 1, step: 0.01, default: 0.5)

mix [MIX]
  a = input1
  b = input2
  c = mixFactor

output [Debug]
  value = mix.result
In this example:
  • input1 and input2 are two sliders that provide the values to interpolate between.
  • mixFactor is a slider that controls the interpolation amount.
  • The MIX node interpolates between input1 and input2 based on mixFactor.
  • The interpolated result is displayed using a Debug node.

​
Best Practices

  • Ensure the c input is always between 0 and 1. Values outside this range will be clamped.
  • MIX is useful for creating smooth transitions, fades, and blends between two values.
  • You can chain multiple MIX nodes together to interpolate between more than two values.

​
Common Issues

  • If the interpolated result is not what you expect, double check that the c input is between 0 and 1.
  • Be aware that the MIX node does a simple linear interpolation. For other types of interpolation, like easing functions, you’ll need to use different math nodes.
