Free One-Click Blender Tool To Snap Vertices To Nearest Surface

Proximity Snap by rinvo has "one job," as the creator puts it: find the nearest other thing and snap to a set distance from it. It only snaps to visible objects, so you can easily limit the targets by isolating your view to just a few objects. It can also handle multiple targets with ease.

You can adjust a range of settings, including the target type (Surface, Edge, or Vertex), distance from the target, direction priority, distance limits, smoothing, and projection mode. Proximity Snap works with Blender 5.0 and above, and best of all, it's completely free.

"With some options, it saves me more time than any Geometry Nodes setup I could come up with to date, and it's not even close. If you ever had to align a bunch of vertices to a set distance from some surface, you know how painful it can be. Setting up modifiers? Referencing the right objects? Or maybe using manual snapping mode? Nah, now it's one button.

Making sure there are no gaps between terrain/road mesh? Also one button now. This one is my personal pain. Honestly I'm always surprised in how many weird cases it helps. 
It automatically finds all nearby objects and can handle multiple of them effortlessly."

This tool aims to deliver pure speed and versatility. The creator says they've been using it a lot lately for retopology, building racetracks, and modeling everything from cars to clothes.
