A Blender™ plug-in for importing LDraw™ file format models and parts.
Import LDraw imports LEGO® models into Blender.
It supports .mpd, .ldr, .l3b, and .dat file formats.
It's intended to be accurate, compatible, and fast (in that order of priority).
- Mac and Windows supported (and hopefully Linux, but this is currently untested).
- Bricksmith compatible.
- MPD file compatible.
- LeoCAD groups supported.
- LSynth bendable parts supported (synthesized models).
- Both Cycles and Blender Render engines supported. It renders either engine from a single scene.
- Import photorealistic look, or Instructions Look.
- Realistic materials including standard brick material, transparent, rubber, and even the less common materials like chrome, metal, pearlescent, glow-in-the-dark, glitter and speckle.
- Accurate colour handling. Correct colour space management is used so that e.g. black parts look black.
- Direct colours supported.
- Back face culling - fully parses all BFC information, for accurate normals.
- Linked duplicates - Parts of the same type and colour can share the same mesh.
- Linked studs - studs can also share the same mesh.
- Studs can include the LEGO logo on them, adding extra geometry.
- Gaps between bricks - Optionally adds a small space between each brick, as in real life.
- Smart face smoothing - Uses Edge-Split Modifier and Sharp Edges derived from Ldraw lines, for smooth curved surfaces and sharp corners.
- Concave walls - Optionally look as if each brick has very slightly concave walls (with the photorealistic renderer), which affects the look of light reflections.
- Fast - even large models can be imported in seconds.
Installing the add-in
- Download the latest version from the Releases page
- Open Blender
- From the Blender menu click: File > User Preferences
- Click the Add-ons tab
- Click the Install from file... button
- Navigate to the zip file you downloaded and select it
- Find Import LDraw in the list of Add-ons (search for LDraw if necessary)
- Tick the check mark next to it to activate the add-on.
- Click the Save User Settings button so that it will still be active next time you launch Blender.
Setting the LDraw Parts Library directory
- Download the latest complete LDraw Parts Library and unzip it to a directory e.g. called 'ldraw'.
- OPTIONAL: Download the unofficial parts and unzip it to sub-directory 'ldraw/unofficial/'
- From the Blender menu click: File > Import > LDraw (.mpd/.ldr/.l3b/.dat).
- In the bottom left of Blender's window, there's a panel of Import Options.
- The first option is the LDraw Parts Library directory. Type the full filepath to the 'ldraw' directory you unzipped to.
- To save that directory and try it out, choose a file to import.

Blender™ is the free and open source 3D creation suite.
LDraw™ is an open standard for LEGO CAD programs that allow the user to create virtual LEGO models and scenes. You can use it to document models you have physically built, create building instructions just like LEGO, render 3D photo realistic images of your virtual models and even make animations. The possibilities are endless. Unlike real LEGO bricks where you are limited by the number of parts and colors, in LDraw nothing is impossible.

Bricksmith allows you to create virtual instructions for your Lego creations on your Mac.
LSynth is a program that synthesizes bendable parts for LDraw files.
