How can I set the gravity vector for a deformable object? I want to apply gravity in the -Z direction, and I'm modifying the code from the deformable object tutorial to achieve this, as I'm working on simulating balloons in the environment.

Can you give a little more info on what you're trying to do? The gravity vector is applied in the -Z direction by default so you shouldn't need to do anything explicit here. I must be missing part of what you're trying to do.

Edit: I read through your post and noticed the balloon detail. If those are the only rigid bodies in your simulation, you should be able to just set the gravity in the physics scene to a negative value. Is that the case or do you have some normal rigid bodies and some bouyant rigid bodies?
