From 04:00 there is a showcase of this tool.

Is there an asset that you can buy that does that? It seems like a really basic tool and I can't believe everyone is supposed to build it for themselves.
I searched tool like that here and on orbolt asset store but I can't find something that would match it.
The closest thing I found to do that is MOPs Shape Falloff but you have to manually animate it. Is there a version of it where it's automatically animated.
