3D mesh distortion and more new 3D shape features!
Not from points you move by yourself in the editor, I think.
If you setup meshpoint positions at the start of the level (with something like a function) you can store the values in an array as well though. It's a bit of a finicky workaround that requires some work to setup however. I did it like that when experimenting with a very simple "rolling hills" tiled background. Maybe there's a much easier way, I have no idea.
If getting the values for meshpoints directly is something that's easy to implement it's a great suggestion.
