Spectacular! This works exactly as I wanted!
I've got two objects on parallel curves traveling side by side at the same velocity. I've got a question however. I've got a lot of these to set up. I'd like to create a compound out of the subtree, one I can reapply to other objects as I get them rigged. I only have one problem, I'd like the curve length to adapt to the path of the object to which the ICE tree is assigned. Is there any way to find that through self? For example, if object is self, and self is animated on path crvlist30, I want self to find crvlist30 and then curvelength. I was unable to find this through explorer and I looked in the object model documentation but I've been unable to isolate anything on the animated object which would point to the path the object is assigned. Any ideas?

Apply a path constraint to get nice things like tangency and up vector for free. 2. Remove the animation on Path %age. 3. Apply an ICE tree to calculate the percentage yourself: get current time (make sure to turn Global on), multiply by desired speed, divide by curve length (this is why you can't do it with a simple expression), multiply by 100 for the percentage, and set self.kine.pathcns.perc. gray From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Ponthieux, Joseph G. (LARC-E1A)[LITES] Sent: Wednesday, June 19, 2013 10:16 AM To: [email protected]<mailto:[email protected]> Subject: velocity I'd like to set an object on a path using velocity, or something similar to velocity at least, as the means of propagation along the path. The idea is to animate a bunch of different objects, while on different paths of random lengths, so they all appear they are going the same speed regardless the path length. I know that I can use velocity as a factor on particles, but these need to be models animated on paths. Is this possible?
