Instancing Trails without feedback in #touchdesigner

Instance trails are additional instances that follow an instance. In this tutorial we build a reusable component with which you can transform any instancing network to trailing instances. Previous popular methods have done this using Feedback to cache the instancing data, but here we use a Cache TOP and replicate multiple Cache Selects which gives us the ability to have a variable trail length regardless of the number of trailing instances (which you could not do with the feedback method).

On Patreon you will find the project file and .tox, as well as a Line Trails variant:
