Is there any way to extrude an object so that all its frames are rendered at the same time? I don’t want a motion blur, I want them all to be there, not blurred.
For example, if a cube moved its width every frame for three frames, I would want a rectangular prism rendered.
yes. see old tutorial on compositing. is done with a wireframe, where you add the rendered strip three times, each one offset by a few frames, then mix together.

Also, you might be able to parent it to a path and use Dupliframes.
Thanks for your help! It works just as I wanted!
