How I can get spline tangent from BP and apply this values on Pawn Roll

Hi guys!!!

I’m doing a job I have to simulate a roller coaster. I used to create the tracks [this tutorial][1] and to the pawn follow this same spline [this tutorial][2]. With minor adjustments.How to make the StartLocation variables, Start Tangent, And Location, End Tangent, StartRoll and EndRoll as public and exposed to the Pawn. In order to access them in the Blueprint Pawn also exposed the LoopCurrentIndex and NextLoopIndex. But I am not able to wagon the banking track rail.


Some one can help-me do this?

Some one!!! Please!!!
