Lego Generator
Turn any UV-textured model into a Lego brick mosaic with one button. Every brick automatically picks up the color of your texture at that exact spot — fully procedural, fully non-destructive, completely free.
One-Click Build · Auto Texture Colors · Hollow Shell
WATCH IT IN ACTION
ONE BUTTON, INSTANT MOSAIC
Select your model, press LEGO — the whole thing rebuilds as a clean grid of bricks, with your texture's colors baked into every single one.
!
IMPORTANT — START BIG, THEN REFINE
A Lego build places a very large number of bricks side by side. To find the optimal count, do your first generate with LARGE bricks , then gradually reduce the size step by step until you reach the right standard for your model and scene scale. Jumping straight to tiny bricks on a big model can mean millions of instances at once — building up to it keeps everything smooth.
SINGLE & MULTI-MATERIAL MODELS
Works whether your model has one texture or many. Each material's color is sampled per brick automatically — no manual setup, no baking by hand.
HOLLOW SHELL & CUSTOM BRICKS
The inside stays empty so your scene stays light — only the shell is built. And you're not stuck with one brick: use the built-in one, any object from your scene, or load your own from an external .blend file.
Everything Inside
Powered by Geometry Nodes — nothing about your original model is touched.
Auto Texture Sampling
Every brick reads the model's texture color at its own position — single or multi-material.
Hollow Shell
Empty inside with adjustable shell thickness — far fewer bricks, much lighter scenes.
Custom Brick Loader
Built-in brick, any scene object, or a brick appended straight from an external .blend file.
Viewport % Control
Preview a fraction of the bricks for smooth editing — renders always show 100%.
Perfect Tiling
Bricks snap into a clean grid — no gaps, no overlaps, on any axis.
Non-Destructive
All Geometry Nodes — one click to build, one click to remove, original model untouched.
Simple N-Panel
