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...
Find it among other great tool in my scripts page.
