if I have a polygon and I need to dissolve just parts of them slowly just like what you can do with a carve node when dealing with curves. I think theoretically you could transform the pieces to ground level and do a boolean operation with a deformed ground plane and move the piece back to original position, but it would be slow and inefficient. Possible vex code?

Yes you can do this with vex…but depending on what you actually have that you want to ‘dissolve’….can have different approach.
