If you work in vfx field then you will appreciate this tool, VTrack is a vertices tracking scripted tool that allows you to track a selected vertex or an averaged vertices position of a deformed mesh (Alembic or point cached) and create a point helper with a backed animation of the tracked position.
You can use it later as a source for your effect ( blood burst, explosion... you name it) or you can turn on that point animation trajectory so you can visualize the animation path of that area in the mesh.
I created it while I was working on a movie lately they provided me with a plane skidding on the ground (Alembic cache file) , and they ask for wheels marks on the ground.
This inspired me writing this useful tool to capture the animation of the ground touching verts of the wheel where I can later convert the animation path into a curve that can be used to model the skid mark.
It's so easy to use, just apply edit mesh or poly to your cached mesh and hit VTrack...
