spline orientation after vellum simulation

[Max Schwugier]

Hello Guys, 

I am looking for a way to fix the orientation on the points after a vellum simulation on a spline. I want to create a rope simulation and afterwards use the sweep node to get some geo around my spline but it turns out there are some weird twists. (check pictures below)

Ill attach the scene file below. (rope_simulation.zip)

any help is highly appreciated.

 

thank you guys so much in advance.

why didn't you use the "orienta longcurve1" node,you got it

for objects without texture and cylinder like,you can use the trick above

but for simulating rope like stuff,using vellum hair instead of cloth is recommended

thank you guys. In my case the orient along curve + sweep worked but i needed to export geo on alembic into c4d. the more elegant way were exporting a spline and using a spline wrap or sweep inside of c4d but then UVs etc are shifting. Imo its a C4D Problem instead of houdini. It seems like c4d cannot read the orient attribute from a spline.

thank you guys for your help, i highly appreciated
