I wanted to do a render with surface edges, but when I go to post effects on the render tab the only option is “surface edges and isocurves”. Is there a way to get rid of the isocurves and render just the surface edges?
Yes. That post effect uses the same wireframe as the one that you see in the viewport using the
Wireframe display mode. When you select the objects and look in the
Properties panel, you can turn off
Show isocurves under “Isocurve Density”. When you then render and turn on that post effect, only the edges of the surfaces will be rendered.
