Hello,

I have made a example file of my question, in this example file I have 3 Curve SOPs that i put into a Foreach.

I was thinking/hoping that the Ray SOP within the Foreach would get each itterations result and Ray against so I could “stack” these skinned Curve's ..but either I am doing something wrong or it wont work? Any suggestions ?

Well after some fiddeling around I got a solution, sharing it here.

Still needs some tweak to make the overlap look nicer but atleast it is heading in the right direction.

Well actually something seems off, the more curve SOPs you add the more apparent the problem is. It is like the current curve only knows about the last skinned one or perhaps the two last ones..since it is missing alot..

See file and image..

Suggestions ?

Togeather with MikePiaxao at work we managed to “solve” it like this. Not a super nice solution since it has to be cleaned up in the end, but still it works.

And here is a update where the curves are now “pipes” and the ground is a tube.

@MagnusL3D: How did you get the tube/cylinder to work? I replaced the grid object in the ForEach with a Sphere object and I did get the curves to conform to that shape but I lost the overlapping effect.

Is there something more I need to do?
