BrickFX is an add-on that converts any 3D object in Blender into a LEGO-style brick structure. The tool features a library of 122 pre-packaged parts across seven categories, with customizable selection and a part creator for adding new elements. Color assignment can be handled through vertex colors, image textures, or random distribution, with built-in options to constrain colors to an official palette or add emission effects.

The add-on handles scattering and placement on the model, allowing adjustments after generation. It supports animated models, simulations, and OpenVDB volumes. BrickFX includes performance optimizations such as camera culling and distance-based Level of Detail controls. A built-in exporter allows the resulting structures to be saved out as LDR files for use in software like Mecabricks.
