To make a spawn trigger spawn you in an alternate gravity, you need to do the following:
- Add the field "g" onto the trigger with a value of "1" or "true"
- Set the trigger's rotation to the opposite direction of the direction you wish to spawn the player. Think of this like a gravity modifier. When the rotation is "1 0 0 0" (default), a gravity modifier will turn you upside-down. Same goes for spawn triggers. An easy way to see which direction you'll spawn is by looking at the Z axis on the axis gizmo. The direction the Z axis is facing will be your "down" gravity.
Here's an example rotated gravity modifier:
Note how it has the "g" field set, and is rotated like how I described above.
