Hello.
How can I taper a cross-section as it nears the end of a curve on which I sweep it?

Many thanks, Buki. A very helpful scene.

I wonder, what if I wanted to scale the cross-section non-uniformly?

Thanks, but unfortunately not. Unless I missed something, in your example all X-sections seem to get scaled in a uniform manner.
I'm sorry, maybe I did not express myself clearly. What I meant is something like this (see picture).
This probably would require three separate ramps for X, Y and Z scale. How to connect them to Sweep node?

Great example! Thank you.
May I ask why did you decide to use VOP SOP to create ramps and pscale attributes, instead of using standard SOP nodes? Does VOP SOP offer better performance, or is it just your personal preference?
