I'm developing a VR "game" in 3D, and I have a separate 2D unity project for it. In the 2D project I want to be able to create Paths (Lines with linerenderer). I then want to be able to export these paths to a file and add it to the 3D Game so that the players in the 3D game can follow these paths on a flat surface in a 3D space (In other words: The path has two dimensions, no player is ever going up and down). Question is: How do I make sure that the position, length, path of the line will be the same for the 3D game. If I use a plane in the 3D game, do I also have to use a plane in the 2D program? Or can I use a grid in the 2D program? I'm essentially trying to make the lines "compatible" between 2D and 3D.
