How to achieve shape blending in V-ray for Maya.

We’re struggling to get a decent shape blending result in V-Ray, as in this video where he uses 3ds Max.

What seems to be the missing piece of the puzzle is the ability to set round edges on a V-Ray edge texture and unfortunately that option is not available in V-Ray for Maya.
Has anyone found a solution for this?

I did something like that a while ago …https://forums.autodesk.com/t5/maya-shading-lighting-and/i-want-to-blend-the-ground-and-the-object/m-p/11646469.., sorry can’t provide more help at the moment I’m traveling.good luck

Thank you! We managed to achieve the result we were looking for with this technique. Much appreciated!
