Hi, I have a spell that spawns a sphere in my hand that can be then used to attack enemies. I want this sphere to spawn smaller and then gradually reach its full size. How would I do that? I’m looking for something similar to”move component to” but instead of modifying the location, modify the size

You can Modify the size by using a set Actor relative scale. You can change the time it takes to adjust Size by using a Timeline or a Lerp depending on how your BP is setup

I set it up like this, the mesh goes immediately to the new size and doesn’t increase gradually over a period of time. How do I set that?

Double-click on the timeline node and you’ll be given a graph. On that graph, add a float track and plot points onto it that will represent scale over time from 0-1. Back on the event graph, you can use the output float as your LERP alpha.
