Can UE interpolate between barycentric vertices?

Here is a video how it works in unity, I Made an F-Zero Game (because Nintendo won't) - YouTube
I also need it for a F-Zero clone would be kinda nice doing the ship rotation like this.

Under “View Mode” - “Ray Tracing Debug” are visualizations of barycentric coordinates. Not sure how to access it in game but you could dig into the sources to see how it is generated.
