How to Animate Alt+S?

Hello fellows! I’m looking for a way to animate the shrink / fatten component in a part of my mesh … I’m not figuring out how to do this even with the AnimAll add-on. Do we have a modifier that does the same thing that Alt-S does? Do we have another way to achieve the “scale along normals” effect? What approach do you recommend me? Thanks!

You may want to look at the Shape Keys.
Perhaps that’s what you’re looking for?

thanks Andrew, this is it :slight_smile: :smiley: !!!

Displace modifier without any texture will do what you want.
