Lerp Node
Description
Returns the result of linearly interpolating between input A and input B by input T.
Unity calculates the output as:
A + T × (B − A)
The value of input T acts as a weight factor applied to the difference between B and A:
- When T is
0, the output equals A. - When T is
1, the output equals B. - When T is
0.5, the output is the midpoint between A and B.
The Lerp node uses Dynamic Vector slots, so A, B, and T always resolve to the same component count, which matches the smallest connected vector (larger vectors truncate). Scalars promote to the resolved size by duplicating their value across components.
Ports
| Name | Direction | Type | Description |
|---|---|---|---|
| A | Input | Dynamic Vector | First input value |
| B | Input | Dynamic Vector | Second input value |
| T | Input | Dynamic Vector | Time value. Typical range: 0 to 1. Though you can use values outside of this range they may cause unpredictable results. |
| Out | Output | Dynamic Vector | Output value |
