i want to have a piece of geo copied and deformed appropriately along a curve, but remain vertical.
Using the orient along curve i get halfway there, but then my geo gets squished at certain areas of the curve.
Essentially my geo has the correct orientation along the curve but has lost its width

In what way do i need to setup the normals so that the result is correct?

Hi,

I would calculate an usual orientation, where v@N is the tangent. After this you can set v@up to Y and recalculate v@N based on the existing one.

awesome, thank you! simplified it a bit, turns out up vector was the main culprit
