Licensing change

Please note that the new code that is currently developed as part of the 2.0 code base is licensed under APL 2, the previous code was and remains GPL.


LuxRender 2.0 API

LuxRender 2.0 is on its way, a thread has been opened to follow development on the new API and features.


New optionally biased path tracing

A brand new integrator is currently being develop to help dramatically reduce rendering times at the expense of some user controlled bias in the rendering. Preliminary results look very promising.


New hair support coming

A much improved hair support is being added to LuxRender. The first results are quite promising.



LuxRender is a physically based and unbiased rendering engine. Based on state of the art algorithms, LuxRender simulates the flow of light according to physical equations, thus producing realistic images of photographic quality.

LuxRender is now a member project of the Software Freedom Conservancy which provides administrative and financial support to FOSS projects. This allows us to receive donations, which can be tax deductible in the US.

Get LuxRender

To get started with LuxRender, choose a package:

Blender DAZ Studio 3DS Max

XSI Maya C4D

Standalone Source Code

LuxRender is free software - both for personal and commercial use - and is licensed under the GPL.

Major features

Changes in the 1.5 version in video.

Physically based spectral rendering

LuxRender is built on physically based equations that model the transportation of light. This allows it to accurately capture a wide range of phenomena which most other rendering programs are simply unable to reproduce. This also means that it fully supports high-dynamic range (HDR) rendering.


LuxRender features a variety of material types. Apart from generic materials such as matte and glossy, physically accurate representations of metal, glass, and car paint are present. Complex properties such as absorption, dispersive refraction and thin film coating are available.

Fleximage (virtual film)

The virtual film allows you to pause and continue a rendering at any time. The current state of the rendering can even be written to a file, so that the computer (or even another computer) can continue rendering at a later moment.

Free for everyone

LuxRender is and will always be free software, both for private and commercial use. It is being developed by people with a passion for programming and for computer graphics who like sharing their work. We encourage you to download LuxRender and use it to express your artistic ideas. (learn more)
