[Updated]Invisible AMFP meshes? (And Other Questions)

[DeAngelo]

New question: How do I make an object float? I've played custom stories with objects that have no gravity and if you grab it and throw it it just sorta floats away. I'm trying to do that. I unchecked the "has gravity" box in the model editor but that did nothing. I tried doing a search but I can only find stuff about floats in terms of scripting.

Edit: Sigh, nevermind. Apparently the object needs to have a mass more than 0 before it will float around. Sorry.
