Grasshopper Voronoi rounded surfaces

Hi Laurent.

I found what i am looking for in another thread of yours.

The polygons look really smooth and are rounded at the edges where they meet.

This looks really good, but the problem I face is that I need a big surface. 5 meter x 4 meter. I can’t seem to scale it. It doesn’t work then.
Also I don’t want the different sizes of polygon cells.

Do you have a solution for this?
