Take a look a picture below.
White square is a shared control point between 2 b-curves which are part of the same spline.
I am generating a mesh around that spline that will act as a floor, but between every ''curves'' of my b-spline the junction is pretty harsh (see picture) and there is overlapping and/or derivative is pretty high which make the path not so soft.
What should I try to soften the result and reduce the overlapping?
