extruded curves changing orientation on render I've followed the usual steps to extrude a curve upon a path. All looks well in the viewport.

Any advice or suggestion appreciated.
One (or more) of your modifiers is disabled for rendering:



Enable it and render happily ever after.



The camera icon toggles the use of the modifier for rendering.
