When creating setups for our tools like Pastiche or Newton for After Effects, we often duplicate things (“I want 800 circular shapes right now!”). The Select All – Copy – Paste sequence has come to an end. This command in the Layer menu allows you to duplicate the selected layer X number of times. Lightning fast.
Multi-Duplicate is part of the MOBO UTILS,
an evolutive set of simple tools for Adobe After Effects.
They do what’s described in their description and nothing else.
