Bricker – Photoreal Lego/Minecraft Simulations

by Bricks Brought to Life in Scripts and Addons

Photorealistic LEGO Models & Simulations in Seconds

Bricker is an addon for Blender that converts any 3D Mesh into a photo-real 3D brick model. You can also use Bricker to generate animated brick models from keyframed animation, simulations (such as fluid, smoke and fire, or soft-body animations), armature, and much more.

3D Brick Modeling Made Effortless

With this addon, modeling and rendering a 10,000 brick sculpture is simply effortless. Once you've created a 3D mesh, a simple click of a button will convert it to a brick sculpture of any scale or orientation. Choose the level of detail (underside, customizable logo, bevel, etc.)materials (source object materials/UV colors, random, custom material, etc.)randomized location/rotation (to mimic real life imperfections)brick type (including bricks and plates, slopes, studs, cylinders, cones, and even custom objects), shell thickness, brick size, connectivity/sturdiness, internal support structure, and so much more with the simple and intuitive UI.

NEW in Version 1.1 – You can now customize the auto-generated model with handy tools like split bricks, merge bricks, change brick type, add adjacent bricks, and more!

3D Brick Simulation in Seconds

Have you ever marveled at the fluid simulations in "The LEGO Movie", or wondered how the animators of 8 Bit Trip created the animated sculptures featured throughout the video? Well, we've created a plugin that solves these problems effortlessly for both CG and stop motion animation, and you're going to love it. Bricker will convert any animation or simulation (keyframes, soft and rigid body physics, armature, fluid, smoke and fire, cloth, parented animation, and more!) into a frame-by-frame animated sculpture that's ready to be rendered or constructed in real life. Here are some awesome examples of what you can create:

NEW in Version 1.4 – You can now brickify smoke and fire simulations! Customize the smoke density, fire color, and fire intensity for exactly the look you want. The results are truly stunning.

The possibilities really are endless – we're excited to see what you'll create!

Stunning Photorealism, Zero Effort

Bricker comes packed with functionality that makes rendering photo-real brick models effortless. Every brick was designed with both efficiency and realism in mind – you get to choose the number of stud vertices, the level of detailing on the brick underside, the bevel width and resolution, the amount of minor variation in position/rotation, and much more – all optimized with smarter, cleaner brick topology than any 3D brick exporter on the market.

NOTE: Combine Bricker with our ABS Plastic Materials for a full library of materials based on the LEGO® brick color pallet.

Highly Optimized, Blazing Fast

Bricker was built to accommodate the workflow of an artist. Every brick model is optimized and cached for fast generation and even faster updates, and with the power of a background processor, the calculations won't interrupt your workflow. The fluid model you see below was generated in under 5 seconds on a Mac laptop.

The built-in mesh generator is memory efficient and able to produce millions of bricks without requiring massive amounts of RAM, with many features including object instancing and selective detailing at your disposal. Rigorously tested and extensively optimized, this addon is built for speed.

Bricker for Model Builders

We designed Bricker to be useful for real-life sculpting with LEGO® bricks as well. Choose the maximum brick size for your model (e.g. 1x8, 2x10, etc.), set the thickness of the outer brick shell, customize the internal support structure (cross-beams, lattice or columns), and generate the model. You can adjust the connectivity threshold to ensure your whole model is sturdy and inter-connected. Once the model is finished, export it to any LDraw compatible program so you can download the instructions and build it in real life!

NOTE: When combined with the AssemblMe addon, you can also generate a step-by-step build animation in Blender to help you construct it.

Bricker for Custom Objects

Bricker can also be used to generate sculptures from any mesh object imaginable! Bricker is useful for any creator, from Lego stop motion/CG animators (like our developer, Christopher Gearhart of Bricks Brought to Life) to Minecraft artists and other Blender enthusiasts alike!

Ever wondered what Mario would look like if he were made out of Suzanne Monkeys? Look no further!

Again, the possibilities are endless. Send us your creations/renders if you'd like to be featured here; we'd love to show off the awesome creations you're able to make!


Future Improvements

We are working to improve Bricker and continue to add the features you've been asking for. Below are the features in development right now:

  1. SNOT (studs not on top) mode
  2. Many more brick types to choose from (e.g. tiles, wings, domes, etc.)
  3. Generate model with bricks and slopes to more closely approximate original mesh
  4. 'Exclusion' option so distinct models don't create redundant bricks when overlapping
  5. Parameters for adjusting offset and scale for custom objects
