true, but it dosn't reduce lag at the begining of the track, just as you get to the end. if there were a way to get the track to apear and disapear as you go along, that might work.
This is just a very fast probe, it executtes a script every collition, and can be usefull in scenes.
Although i have seen and used the K-probe,( it is great!) it wasn't until after i made this that i really looked at how the k-probe did its super fast colitions. I tested it with this one and they run at about the same speed.
It just shows you diferent linkages and how they work, as for the hinges, I'm guessing it's probobly a bug with algodoo, as it work with some and not with others...
