Align To Spline Xpresso
Align to spline is no doubt an expression that most Cinema4D artists will have used at some time or another. The problem with the built in expression is that it is clamped and you can only animate the position parameter from 0% to 100%. If you want the object to loop or wrap around the spline it is not so simple.
There are other solutions available within the application, you could use MoGraph and clone onto a spline. Then use the offset parameter. However in this tutorial, I show you how to build a loopable align to spline expression using just Xpresso. The advantage here is you can use this setup with the most basic install of Cinema4D and also the object is still in it’s original state as it hasn’t been passed through a generator.
I show you how to include a tangential option and the addition of a pop-up menu to define the axis you would like to align.
Anyway enough of my waffle. Check out the tutorial below or click through and watch it over on the helloluxx channel on Vimeo
