Does Blender has something similar to this tool from the Cinema 4D webiste. It looks pretty useful. I’ve heard of vertex painting in Blender and didn’t know if it was related.
It has nothing to do with vertex painting (you’re thinking of weight painting for armatures). But yes, you can do this same thing with nurbs in blender. The option is in the edit buttons when you’re in edit mode for the nurbs object. (I don’t have blender in front of me, so correct me if I’m wrong)
I don´t know you one can achieve the same effect, but this could be done by giving diferent weights for indivisual NURBS curves in the model.
In the exemple above we see the “weighting” in a Subdivison surface (Blender doesn´t have this feature - Maya does have, it´s called sudb creasing, where you can )
