I’m not exactly sure what you mean by floats down to floor, you can spawn the player exactly where you want it.
As for Hiding the screen. UMG Widget is what I use in my current project, I remove it when I’m ready to start.
In past projects I have had a special staging area off to the side, basically a box with no light in it and have the camera in there, then when ready teleport to the correct position.
Those are two ideas. It really depends on how you start your level. Another idea is to use a particle effect, so use the Spectator Pawn / Camera to view the start area, but then spawn the character in with an effect.
