Lego Generator earns its place in the superhive library for doing one specific job with a single button: converting a UV-textured model into a brick mosaic that reads its colors straight from the texture, all through non-destructive Geometry Nodes.
Lego Generator is a Blender addon that turns any UV-textured model into a grid of Lego bricks. Select a model, press the LEGO button, and the whole thing rebuilds as a clean brick mosaic with the texture's colors baked into every piece. It runs entirely on Geometry Nodes and works whether your model uses a single texture or many materials, sampling each material's color per brick automatically.
Bricks snap into a clean grid with no gaps or overlaps on any axis. A hollow shell option leaves the inside empty with adjustable shell thickness, building far fewer bricks and keeping scenes lighter. You aren't limited to the built-in brick either: use any object from your scene, or append one from an external .blend file. A viewport percentage control previews a fraction of the bricks for smooth editing, while renders always show them all.
Everything stays non-destructive, so one click builds and one click removes, leaving the original model untouched. It requires Blender 4.2 or newer, a UV-unwrapped model, and texture-based materials for the color transfer. Released free to the Blender community by 3DRedbox Studio.
Lego Generator is best for blender artists who want to turn UV-textured models into procedural, non-destructive Lego brick mosaics.
Lego Generator is completely free to download and use.
Lego Generator is built for Blender 4.2 and up, and the developer notes it was built and tested on 5.1, with support listed across the 4.2 to 5.2 range. So Blender 5.1 falls within the supported versions. The whole addon runs on Geometry Nodes. If you're on an older release, you'd need to update Blender to at least 4.2 first. For the most current version details and compatibility, check the developer's page.
Lego Generator needs your model to be UV-unwrapped, and it relies on texture-based materials to transfer color into each brick. With those in place, the addon samples the texture color per brick automatically, whether the model uses a single texture or many materials, with no manual baking or setup for the color transfer. If a model isn't UV-unwrapped or lacks texture-based materials, the per-brick color sampling won't have anything to read from.
Lego Generator places a very large number of bricks side by side, so the developer recommends starting with large bricks on your first generate, then gradually reducing the size step by step until you reach the right scale for your model and scene. Jumping straight to tiny bricks on a big model can mean millions of instances at once. The viewport percentage control also lets you preview a fraction of the bricks while editing, while renders always show all of them.
Lego Generator isn't limited to a single brick shape. You can use the built-in brick, swap in any object already in your scene, or append a brick straight from an external .blend file through the N-panel. The hollow shell option keeps the inside of the model empty with adjustable shell thickness, which builds far fewer bricks and keeps scenes lighter. Everything runs through Geometry Nodes, so you build with one click and remove with another, leaving the original model untouched.
Lego Generator is listed as free here, released to the Blender community by 3DRedbox Studio under a GPL license. For current licensing and any terms, it's worth checking the developer's page directly. Since it's a Geometry Nodes addon, building a mosaic is non-destructive: one click builds the bricks and one click removes them, leaving your original model intact. A demo video is also available if you want to see the addon before installing.
