Origin Align stands out in the superhive library for handling origin placement across the bottom, top, sides, and faces of a mesh, with a Smart Center version for geometry-aware centring.
Origin Align gives Blender users control over where an object's origin sits. You can set it to the bottom, top, or any side of a mesh, then snap that origin to the floor, ceiling, or wall of another mesh with precision. A Grid option snaps the origin to the closest point on the grid.
Before aligning, you can center the object's origin so it lands at the middle of the base rather than simply snapping to it. In Edit mode, you can align the origin to a selected face. The add-on ships with documentation, and a demo video is available.
A separate Smart Center version takes into account where the mesh sits on a given side. It analyses the geometry on the assigned side and centres the object accordingly. With a wall-mounted light fixture, for example, it aligns the origin with the geometry at the arm's end, where the standard version would snap to the given side instead. This helps with complex or asymmetrical objects.
Origin Align is best for blender artists dealing with assets whose origins sit in the wrong places, and those aligning complex or asymmetrical objects.
Origin Align is completely free to download and use.
Origin Align lists support for Blender versions 2.93 through 5.0, covering a wide span of releases. That range spans older 2.9x builds as well as recent versions, so if you run a build inside that window the add-on should install and function as described. For confirmation on your exact version, check the developer's page before installing, since compatibility details can shift as new Blender releases arrive.
Origin Align is distributed under the GPL license, according to the details listed for the add-on. Within this catalog, Origin Align is listed as free, though licensing terms and any purchase options may differ on the developer's own store. For the current terms directly from the creator, visit the developer's page, since the details there take precedence over what you see here. Checking before installing helps you confirm how the add-on is licensed for your use.
Origin Align can align an object's origin to a selected face while you work in Edit mode. Outside of that, it also sets the origin to the bottom, top, or any side of a mesh, and can snap it to the floor, ceiling, or wall of another mesh. A Grid option additionally snaps the origin to the closest point on the grid, giving you several placement targets depending on the task.
Origin Align: Smart Center is a separate version that takes into account where the mesh sits on a given side. It analyses the geometry on the assigned side and centres the object based on that geometry, rather than snapping straight to the side. With a wall-mounted light fixture, for instance, it aligns the origin with the geometry at the arm's end. This makes it useful for complex or asymmetrical objects where the base doesn't line up with the bounds centre.
