Well, I couldn't leave it at that. Here is a more optimized version with reseeding. The main issue with this method is that when disconnected areas of the point cloud appear and disappear, the tracking breaks down. This is not a perfect solution, but I think you could use it to generate a decent velocity field....

Do you know a way to do this same thing but where points are not just on the surface but following the whole volume?
So as to have "bubbles" inside this vdb character?

Is it possible at all to change the location for autosave? I always have autosave go to wherever my houdini file is inside a "backup" folder but would love to be able to change the directory.

Thanks a lot in advance!
