What are exacted differences between Origin,Center and Position of an actor?

By the way, if you want to place the center of your plane at a particular position in world coordinates, here is a recipe to do so:

  1. Call GetCenter() on the dataset (not the actor itself) to get the center in model coordinates
  2. Call SetOrigin(center) to set the origin to this center that you just got
  3. Given the world coordinate point (P[0], P[1], P[2]) where you want to place the center, call SetPosition(P[0] - center[0], P[1] - center[1], P[2] - center[2]).

This will place the center of the actor at P, unless I made some silly mistake with the math…
