Wireframe Render

Under your render settings (Or Output settings), simply click Render Wireframe Fast or Render Wireframe Slow to render out a PNG Sequence to the designated Output folder.

Render Wireframe Slow : Renders wireframe as PNG Sequence with full compression (Costs less storage as images will be compressed)

Render Wireframe Fast : Renders wireframe as PNG Sequence with no compression (Costs more storage as images will be larger)

Warning : You can not cancel the render process after pressing Render. It will render the frame range you have set in your timeline. It doesn't take long, its as fast as an OpenGL Render, so will only take long if your scene is extremely heavy
