I have a question about rendering an animation.
For a research project I am trying to animate displacements on a steel frame. This steel frame has vertices and edges.
In my script I just updated the vertices' x coordinates and then keyframe it. The animation I get in object mode is really what I wanted to have but if I try to render this animation it doesn't work.
I think it is because of the non defined faces but is there a way to render a mesh which only has vertices and edges? (In object mode I can see the animation.)
(Note that this is not the whole script because the creation of the keyframes and the animation in object mode works.)
