is there a motion trail plugin that supports riggify?

the title speaks for itself.

I’m working on a major animation project, my graduation thesis, and we are deep into animation.
However, reaching the spline stage has become a very tedious task having to animate without light table or a working motion trail.

any idea if there’s an updated version of motion trail that supports riggify?
any tips for smoothing my animation are welcome as well.

thank you!

You asked the question in the wrong section. However…

thank you for the help, and sorry for misplacing my question, as far as I understood this was concerning animation so I posted here. this probably should have been placed in a more technical section.
