However, i am unable to find any relevant results.
An example of dropline and trail line are illustrated as the red lines in the following picture.
spontaneously I'd say this should work by creating those lines manually every few animation frames. So during the model animation at regular intervals you'd sample the location and then update the trail line by adding this new vertex and creating a drop line. Did you try that? Feel free to share a code snippet with me and let me know if smth doesn't work.
