I am trying to render some simple geometric form using freestyle in Blender. But parts of some edges are missing - even though I have marked freestyle edges. Does anyone know how to fix this?
The issue seems to stem from the scale of the object. While you've set the unit scale down, it's still large in Blender units. I suggest setting the unit scale back to one and scale the object to the size in millimeter that you were intending. This results in correct freestyle edges.
