What's LegoToR

LegoToR delivers the core for rendering LEGO Digital Designer scenes including advanced shaders, lights, and geometry with RenderMan

Release Notes

Open for Everyone

LegoToR relies on open source tools so you can enhance it at your will and render complex LEGO environments with maximum flexibility

Pixar Technology

Now you can get out-of-box production tools straight from Pixar Animation Studios, including materials and light transport... no development required.

Photorealistic Images

Physically based shading allows RenderMan to deliver highly realistic lighting with minimal setup, including full support for multi-bounce ray traced global illumination and ray traced subsurface scattering. Much research and development has gone into making these traditionally expensive effects a production reality. Pixar's first feature film to use this technology was Finding Dory, and now it has matured with great developments in Cars 3, Coco, and Incredibles 2.

"Nice work... it inspired me to create such thing for a 3D Studio Max."

Advanced renderer

LegoToR relies on RenderMan rendering technology which has been used in blockbusters such as Toy Story, Jurassic Park, Avatar, and The Lord of the Rings.

RenderMan - 30 years in rendering

RenderMan is a proven rendering solution and delivers high quality output for studios such as Pixar, ILM, Animal Logic and many more. RenderMan has been used to create visual effects for major blockbuster movies such as Terminator 2: Judgment Day, Toy Story, Jurassic Park, Avatar, Star Wars, and The Lord of the Rings. LegoToR now provides you with a solution to render your LDD files with the same power as Hollywood.

Checkpointing

LegoToR can resume interrupted renders via RenderMan, redefining the creative process.

Happier Dailies

Checkpointing allows the renderer to make repeated passes over the image, refining it a bit more with each pass. While the image will be quite noisy during the initial passes, it is usually sufficient to give an impression of how the final image will look, instead of having to wait for a final frame, allowing reviews and more iterations of your scenes.

Digital Bricks

Better Brick Materials

RenderMan was the first VFX commercial renderer in the industry to ship with a physically based model for subsurface scattering, a truly accurate model for photorealistic skin based on deep path tracing and albedo controls.

SSS Deep Dive >

Until now, the implementations available to the VFX industry for these effects have been substantial approximations, which inherently produced errors and artifacts. RenderMan's new subsurface approach significantly increases quality and realism when rendering skin and other soft or delicate materials, which is essential for creating believable characters.

Secondary Passes

RenderMan AOV and LPE passes provide robust workflows for compositing feature animation and VFX.

Compositors Rejoice!

RenderMan provides elegant methods for breaking visual effects down into secondary passes for compositing, including DeepEXR and Cryptomatte support. With support for both AOVs and Light Path Expressions, RenderMan offers a multitude of ways of writing any element of a render (SSS, Diffuse, Shadows, Z-Depth, Object IDs, Per-Light AOVs, etc.) into many popular formats.

Performance

LegoToR is up to 2x overall faster then other solutions, thanks to using RenderMan architecture.

"Imagine if LEGO would release an app that could show you what the set look like in AR 😱 that would be amazing!"
