Why we like it

Ground Modifier stands out in the Superhive library for its dynamic approach to snapping, applied through a standard modifier that also supports animated geometry.

What is Ground Modifier (Dynamic Snap To Floor Or Surface)?

Ground Modifier is a Blender add-on from CGMatter that keeps geometry resting on the ground. Unlike standard snapping alternatives, it is fully dynamic: it handles any geometry, any object transform, and animations too. It works as a standard modifier, so you drop it in like normal and stack effects alongside other modifiers.

The add-on includes a custom z-height parameter, letting the ground sit at values other than z=0. An optional surface option (marked experimental and slower to calculate) lets you snap to a chosen surface; when no surface is selected, the modifier defaults to the standard flat ground. For the surface option, the developer notes your object should sit significantly above the surface along the z-axis while using the modifier.

Common use cases include keeping furniture and similar objects exactly on the floor, correcting armature animation foot clipping, and rolling animations. The add-on is bundled with Genie. Documentation and a demo video are available.

Frequently asked questions

What Blender version does Ground Modifier require?

Ground Modifier is installed just like any other add-on: drag the .zip right into Blender 4.3 or above and hit accept. It is listed as Blender Extension compatible, with an extension type of Add-on. If you follow the standard drag-and-drop installation into a supported Blender build, the modifier becomes available to drop onto your objects and stack alongside other effects. Check the developer's page for the latest compatibility details before installing.

How does the surface option in Ground Modifier work?

Ground Modifier added an optional surface option in its v1.2 update, letting you snap to a chosen surface rather than the flat ground. It is marked experimental and is slower to calculate. If no surface is chosen, the modifier defaults to the standard flat ground. The developer notes you should make sure your object is significantly above the surface, relative to the z-axis, while using the modifier. When you need a plain floor instead, leaving the surface unset keeps the standard behaviour.

Can Ground Modifier snap to a ground level other than z=0?

Ground Modifier added a custom z-height parameter in its v1.1 update, so the ground can be set to values other than z=0. This lets you position the resting plane where you need it rather than only at the default. Combined with its dynamic handling of any geometry, any object transform, and animations, this gives you control over where objects come to rest while keeping the workflow inside a standard stackable modifier.

Is Ground Modifier free?

Ground Modifier is listed as free in this catalog. It is distributed under the GPL license and is bundled with Genie. For current licensing terms and any pricing details, check the developer's page directly, since these can change over time. Installation follows the normal Blender add-on process, so once you have the file you can drag the .zip into Blender and accept to start using the modifier.
