Why we like it

Field Grid earns its place in the Superhive library for turning a mesh into an editable lattice with a single operator, keeping every parameter live through Geometry Nodes.

What is Field Grid?

Field Grid is a Blender extension from ATDIGIT that transforms any mesh object into a 3D lattice of spheres, cubes, or points. Using raycast detection, it automatically works out which points fall inside the object and which fall outside, styling the two differently — inside particles sit larger and more prominent, while outside points form the surrounding field.

The entire effect is built on Blender's Geometry Nodes, so it stays procedural and non-destructive. You add it with a single operator, then open the redo panel to adjust grid size, field size, element radii, positioning offsets, element type, and inside/outside colors. Because parameters live in the Geometry Nodes modifier, you can keep tweaking the result long after the operator finishes, and you can even plug in custom objects instead of the built-in presets.

Field Grid suits scientific visualization, drone show planning, motion graphics and VFX, abstract and generative art, and educational content. It ships as a single Python file with no external dependencies, runs on Blender 4.2 and newer across Windows, macOS, and Linux, and includes documentation and free updates for compatible Blender versions.

Who is Field Grid best for?

Field Grid is best for blender artists building scientific visualizations, planning drone formations, or creating motion graphics, generative art, and educational content from mesh objects.

How much does Field Grid cost?

Field Grid is completely free to download and use.

Key features

  • Raycast detection that automatically distinguishes points inside the mesh from outside points and styles them differently
  • Fully procedural, non-destructive Geometry Nodes — parameters stay editable in the modifier after the effect is applied
  • Element types include sphere, cube, and point cloud presets, with support for custom objects via the Geometry Nodes modifier
  • Redo panel (F9) controls for grid size (3–80 points per axis), field size, inside/outside radii, and X/Y/Z positioning offsets
  • Customizable inside and outside colors, with inside particles larger than outside ones
  • Toggle for outside grid visibility, plus a Hide Target option that auto-hides the original object
  • Single Python file with no external dependencies, working offline on Windows, macOS, and Linux

Frequently asked questions

Does Field Grid work with Blender 4.2 and later?

Field Grid runs on Blender 4.2 and newer versions. It ships as a single Python file with no external dependencies, so it works completely offline once installed. The extension supports Windows, macOS, and Linux, meaning you can use it across platforms without extra setup. Free updates are provided for compatible Blender versions, so as your Blender install moves forward within the supported range, the extension stays usable. Check the developer's page for the latest details on supported releases.

How do I add Field Grid to an object?

Field Grid works through Blender's Add menu. Select any mesh object first, then press Shift+A and choose Mesh → Field Grid to generate the lattice. Once the operator runs, press F9 to open the redo panel and fine-tune parameters like grid size, field size, element radii, and positioning offsets. It works with any 3D mesh, from primitives and logos to characters and sculptures. The original object auto-hides once the lattice is generated, though you can uncheck Hide Target if you need it visible.

Can I still change Field Grid's settings after applying it?

Field Grid is fully non-destructive because everything happens through Blender's Geometry Nodes. After the operator finishes, you can keep adjusting parameters in the Geometry Nodes modifier panel at any time — grid density, field size, element radii, element type, offsets, visibility, and inside/outside colors all stay editable. Nothing is baked or locked in, so you can iterate on the look as often as you like. You can also plug in custom objects through the Geometry Nodes modifier instead of the built-in sphere, cube, or point cloud presets.

What mesh types work best with Field Grid?

Field Grid works with any 3D mesh — primitives, characters, logos, sculptures, and more. That said, closed, manifold (watertight) geometry gives the cleanest inside versus outside detection, since the raycast algorithm relies on a well-defined interior to separate inside points from the surrounding field. For previewing, the developer suggests starting with a lower grid size, around 15 to 25, then increasing it for final renders. After changing grid size, adjusting the element radii proportionally helps keep the visual balance. These practices produce the most reliable results.

Is Field Grid free?

Field Grid is listed as free in this catalog. It includes the extension as a single Python file, documentation and a README, and free updates for compatible Blender versions. Support is handled through the Superhive chat on the product page, with general inquiries directed to the developer, ATDIGIT. For the most current licensing terms and any changes to how it's distributed, check the developer's page directly, since availability and terms can change over time.
