Hi there, I am currently working display MRT lines in Unreal.

I managed to get the color and update spline in the editor mode, it works perfectly fine. However, when I package it out, the spline appears grey (Color not updated) and the rest of the blueprint afterwards can be executed as well.

Below is how my blueprint looks like, it is in my blueprint class Event graph. Is there other way to set the different color of my spline component?
