The feature to change at runtime doesn't exist, so logically one would look for other ways to simulate the effect..
Thats the confirmation I was looking for. I thought it may exist in the sdk but I couldn't find it, thought I would check.
There are plenty of reasons to want to change polygons directly rather than having transforms control them. More from a procedural standpoint, trying to avoid editor side work. Its not something that is needed* but that would be nice.
Rotating combined with resizing works to an extent to solve the problem but again requires more programming work, at least in the sense I need to do some trig to ensure proper placement rotation and stretching.
