Twisting a sweep

Recommended Posts

Hi guys,

the title is probably not clear enough, so here's the explanation. I want to twist a sweep, defining an upvector, that rotates based on the tangentu vector. In the file I have set the tangentu as N in the polyframe node so the sweeped objects are oriented along the circle. I want to animate the upvector, so that every instance rotates along its normal but i have had no luck so far. there probably is an easier way to do this, but i want to figure out how to do it this way just as an exercise. Any help would be much appreciated.

Hello Kalin welcome to the Forum!

You can use the copy to points and skin sop to do this effect. I know I have an example of it I stashed here in this thread. It even does UVs.
