The teleportation system uses a raycast against collisions to find the endpoint, and the navigation mesh system to find an empty location for the player to fit in. To use it as-is, you would need to generate a collision mesh from the point cloud. This is a non-trivial task, and I don’t think there are any readily made solutions for Unreal available.
An option would be to write a custom raycast algorithm that checks for proximity to the points, and modify the teleport system to use that instead.
A much simpler solution would be to use an alternative locomotion method instead, such as world grabbing, or thumbstick movement.
