Gravity Methods

Hi,
I’m trying to create a particular effect in one of two ways.

Either A: create a volume that lowers or adjusts gravity within that volume.

Or B: Lowers world gravity, but limit player jump height.

Any ideas on how to do either of these?

Adjusting WorldZ is the obvious one, but it affects the player, when I want it to affect the world but NOT the player.

Tried creating a water volume but it didn’t create the effect I was looking for.

Change the players fall speed to get rid of gravity difference?

Good idea. Where?

Character movement component in the character BP, also be aware that there still may be a better method than what I am suggesting.
