Hi, I'm trying to build a digital asset. Basically I got what I wanted in first and second pic. But when I try to add variation with randomizing rotation in y axis the result I'm getting in second input on switch node brokes (third pic). I understand why this is happening but I have no idea how to do it differently. Any help appreciated and sorry for my English.

Post a hip file

But essentially
- if the orient along curve is outputting only N in rolled bitangent direction, then make your Randomize_y_rot output random v@up vector in xz plane

- if orient along curve is outputting full p@orient then append your randomize_y_rot and make it rotate incoming p@orient around it's local axis of your choice by random amount

Hey tamte. this is the hip file. I replaced assets with tube to make it easier.

I see you are using p@rot for additional orientation
you can do that however p@rot is applied after p@orient, so you may need to swap them
make your randomize_y_rot create p@orient
and orientation along curve create p@rot
