    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

This kit extends the math node library available to Blueprints under the "Math Extended" grouping. This has many abstract uses, as well as enabling smoothed movement of actors from one position (vector) to another! Includes Vector Interpolation using Perlin Smooth Step, Linear Interpolation, and Quaternion rotations. Additionally, Inverse square falloff, Smooth Step compensation nodes, and other utility functions are included. These are especially excellent for smoothly animating actors from one location to another, and a demo of this feature can be seen in the documentation.
