Yes, packing each spline separately before merging them for the output node was what worked for me.

I would add to this solution one important step: you have to turn off "Create Packed Fragments" if you are using Pack node.

edit - I found a solution - I had to generate a fake N from orient inside Houdini and export both orient and N, then I used this normal as Look at the direction in “orient mesh to vector” module + orient as quaternion override + N as reference axis vector + 1 override incoming orientation. This feels like an overly complex answer to a simple rotation question.

I found a simple solution:
In “Orient Mesh to Vector”
1. Apply @up to ‘Look at Direction’
2. Apply @N to ‘Side Axis Direction’
