I came across this useful video tutorial on Twitter. Thanks to Tim Clapham of helloluxx for the link. In this video, Joe Lilli of Break into Motion Graphics shows you how to “Force Quit” and “Save” a frozen After Effects project.
Align To Spline Xpresso
In this tutorial, Tim Clapham from helloluxx.com takes you step by step through the process of building an align to spline expression using Cinema4D and Xpresso.
The advantage of this set up over the built in expression is that the position along the spline is not clamped between 0-100%, therefore the object can be looped along the spline multiple times. Tim also adds a tangential option with a parameter that allows you to define the axis used for alignment.
