| During the variable "native" ticking we have to interpolate between the previous steady state and the next one. It's up to the user to do the actual interpolation but Apparatus provides a functional basis to do this. | During the variable "native" ticking we have to interpolate between the previous steady state and the next one.

| | This node returns the ratio of the current variable tick in relation to an active steady frame it resides within. For a better understanding see the following schematic: |

| | This ratio, which is bound from 0.0 to 1.0 (both inclusively), can be used to interpolate the animated visual feedback of some value based on its previous and the next state. In order to achieve that, your steady ticking mechanics have to prepare both states during their processing, while perhaps swapping the past state with the future one. The usual variadic ticking then can use a [[https://docs.unrealengine.com/en-US/BlueprintAPI/Math/Float/Lerp/index.html|Lerp]] node to implement the actual smoothing. |
