Thank a lot !!!
It seems to look like it would be very good to use for mechanical devices (from the screenshots)
I wonder if the movement can be converted to IPO curves so it can be used in the game engine.
Hi Snark. A really useful constraint. And it works fine for me. You have to send a patch in with this.
