Ok I didn’t know that it was normal for debug calls for controllers and base stations to not follow.
As the moving platform I thought more something like a vehicle (train, or something like Hover Junkers). My first reflex was also to create a volume around the platform but I did not pushed the idea further.
I did not test it enough to encounter the ground level problem but probably Paul’s teleport is the best solution.
I’ll do an updated video to show features / problems for fellows devs who did not received their Vive yet.
