The position data of all celestial bodies is pre-calculated in Matlab simulator that takes account of all the physics. I only want to visualize that data. I can have the velocity vectors as well. So taking the first option, what do you mean by rotating a vector?. I mean I’m new in UE4 and I don’t know what function does that. In the past I tried to animate an aircraft with simulated data and the motion was very sharpy. I want to see a smooth movement. The best option that i had found was using timelines with loaded curves. Thanks for the help.
