Teleport and tiled lanscape world composition

Hi, just this question.
How Can I properly teleport a player to a location in a Tiled landscape and avoid the character to fall into the void because the tiled landscape didn’t stream at time?
I can do a lot of hacky things. But is there a proper way to do it ?

thanks

Do you mean that the landscape itself doesn’t load in by the time the player spawns or, even if it does, the player still falls through?

Does the landscape have a collision mesh generated?

I manage to workarround this by disabling gravity for a second or two, but its hard to believe there is no “correct” way to do it.
