A powerful plugin that lets you create polygon shapes similar to sprite mesh but easier to use and supports holes.
Yes they become 2 segments of the same object. If you want them to be 2 separate objects you need to use the action to save the segment to a string variable, use the action to delete the segment from the original shape, create a new black shape, and use the action to load the segment from the string variable into the blank shape.
I am currently adding physics to the object and making good progress.
There is also a bug where when you cut a shape the new segment is not being rendered. I'm working on a fix.
