Join Rob Garrott for an in-depth discussion in this video Linking objects to points with Xpresso, part of CINEMA 4D Essentials 8: Character Rigging and Xpresso.
The scripting language and nodes in XPresso allow you to control objects, but…they also allow you to control the components that make up objects.…What we're going to do is link the position of a point on a spline to the…position of a sphere.…It's an important idea that introduces you to the concept of a point index.…In this scene, I have a very simple hierarchy for a spline wrap and a matrix…object, and I built a hierarchy similar to this in the module on MoGraph.…So if you're unfamiliar with this setup, you can take a look at that, and you'll…see this exact same rig, except that I've made a train.…
But in this case, I've got a little train of spheres, and if I go to my spline…wrap, you can see that if I adjust the Offset, the matrix object will move along the spline.…Now you may have noticed that the spheres are not moving to the position of the…matrix object right away, and that's because of the way the Object Manager…evaluates the objects in the scene.…So the fix for that is to hit the letter A on the keyboard, and that will cause…
