物理基础渲染器「LuxRender v1.3」也支持通过OpenCL进行高速GPU处理，是开源软件，可以免费使用。
※已发布1.3正式版。感谢藤堂++さん提供信息。
从1.3RC2开始的变更点:
– SLG renderer will now accept moving objects, but they will be rendered without motion blur
– more fixes to subdivision surfaces (hopefully no crash should happen anymore)
– support for thickness variation along hairs
– lens effects can now be configured from the scene file
– better parameter mapping for SLG renderer
– improved volume export for Blender
– improved hair export for Blender
– lens effects export in Blender
– fix IOR selection in Blender
– fix wood texture export in Blender
– OSX specific fixes for SLG
从1.2.1开始的其他变更点:
– Improved support for Strands (hair).
– Support for vertex colors and alpha.
– Improved lower bound on glossy roughness (0.000001 vs old limit of 0.006), can be made mirror-like now.
– Better out-of-gamut color clamping.
– New “darken” color clamping mode.
– New “abbe” fresnel texture for specifying IOR using Abbe numbers.
– New false color tonemapper.
– New obstacle-map based glare, much faster and much better looking.
– New “heterogeneous” volume type (for smoke etc), along with 3d textures “cloud”, “exponential” and “densitygrid”.
– New “autopowerimp” light strategy.
– New Catmull-Rom and Blackman-Harris pixel filters.
– New renderer “slgrenderer”, which integrates the SLG rendering engine in LuxRender (not interactive though).
– LuxRender now also has “sobol” sampler, faster alternative to the “lowdiscrepancy” sampler.
– Arealights can now be instanced, this allows for motion blurred lights.
– Support for deferred loading of meshes.
– LuxRender executable location has moved to addon preference panel, see Blender Addon page in user preferences.
– Support for node editor!!! Note this is still under development, which may later render your node materials invalid, so use for testing/playing only at this time please.
– support for bump and normal maps when using the mix material and the SLG renderer
– fix for the MQBVH accelerator in SLG when all primitives have the same bounding box
– improved preview in Blender (faster and more accurate)
– fix normal generation for loop subdivided meshes and make loopsubdivision more robust (it should no longer hang nor crash)
– make the IES parser accept more valid IES files
– properly compute sky power so that it can be used with importance light sampling strategies

LuxRender v1.3 release
LuxRender是免费软件，并在GPL许可下公开。
支持的OS:Windows,MacOSX,Linux
要在3D应用程序中使用LuxRender，需要将场景转换为LuxRender格式的插件。
提供了用于与各种工具联动的插件。
Blender,3dsMax,SketchUp,Cinema4D,DazStudio,SoftimageXSI,Poser,Carara
嗯？仔细看官方页面上没有Maya用插件啊。意外……
找了一下，发现了名为LuxMaya的东西。这能用吗？
话虽如此，这个渲染器从很早以前就有了，不知不觉已经到V1以上了……
我最后一次接触还是V0.8。
这是可以免费使用的高质量渲染器。
没用过外部渲染器的人，不妨试着用一次看看。
顺带一提，读法似乎是Lux（ルクス）。Lux渲染器
因为某款洗发水的缘故，我一直都读成LUX渲染器！(# ﾟДﾟ)
虽然有点老了，不过贴一下视频吧
Blender+LuxRender的组合经常能看到。
Lux+AR
