I was trying to add some polygons.
Then, I found a issue.
Please see this pic.
White lined polygon is truly pos and size polygons.
But practically, it appeared in another place and any vertices was removed.
An issue point I found is in PloygonShape.cs line 100.
It’s “_vertices = GiftWrap.GetConvexHull(_vertices);” and this method remove vertices.
So, how to resolve this problem?
