라이트웨이브용 GI 랜더러 Kray 의 2.0버전이 정식출시 되었습니다. 플러그인으로 혹은 단독실행버전으로 사용이 가능하며 판매가격은 319유로입니다. 윈도우 및 맥OSX 가 지원이 되며 라이센스당 무한대의 랜더노드가 지원이 되며 프로세서및 코어 갯수의 제한이 없습니다.


Kray is a state of the art Global Illumination renderer that allows very fast and accurate rendering of scenes where indirect light plays important role. It includes advanced modern algorithms and optimizations that allow it to render full global illumination, reflections, refractions and caustics very fast even on standard computers.

It is currently available as a LightWave3D plugin and as a standalone application. It integrates tightly into LightWave3D and supports most of LightWave3D features and it's being constantly updated with new ones. However, Kray is not limited to LightWave3D architecture and provides you powerful features which are not available in LightWave3D like powerful tone mapping, instancing and linear workflow.
It is also very easy to port Kray render engine to any software via Kray SDK and KrayScript.


Extremely Fast Computing of Global Illumination
Kray is one of the fastest global illumination render engines around. It features photon mapping and final gathering to provide blistering fast global illumination computation. It also offers uncached final gathering and path tracing for high quality and easy to use rendering.

Fast reflection and refraction blurring
You no longer need to worry about long render times when using reflection blurring. Kray offers extremely fast rendering of blurry rays so you can use them everywhere without the fear of long render times. To speed rendering up even more it is even possible to adjust blurring rays per surface!

Easy linear workflow
With Quick Linear Workflow plugin you can easily convert all your incoming textures and images into linear space and therefore utilize the power of true linear work flow. It's all done with just a few simple clicks.

Powerful instancing
Kray instancing enables you to render millions of instanced objects so you can effectively render many billions of polygons without using much memory. You can also use powerful instancing plugin to help you position instances randomly in space with just a few mouse clicks.

Physical sky
Physical sky is a powerful feature that allows close approximation to real life sky and sun lighting. With Kray physical sky you can quickly get correct sun and sky look of any place on earth at a chosen time and date.

Powerful tonemapping
Several tone mapping modes inside Kray offers you wide range of tone mapping possibilities. You can use one of the default tone mappers (linear, gamma or exponential) or use a Tonemap blending plugin which allows you to mix tonemapers between each other. This gives you wide variety of possibilities to adjust the look of your rendering.
Powerful optimizations

Even though Kray is easy to use with default presets and settings you are able to optimize almost every part of the engine by tweaking the individual settings. More advanced users can also customize Kray user interface to their liking and explore advanced features of Kray Script which offers many powerful possibilities.

Complete feature list:

Global illumination

  • full global illumination, includes many ways of light transport

  • photon mapping: a number of ray bounces has small influence on rendering speed (good for scenes with many ray bounces)

  • light mapping: similar to photon mapping, but with many advantages

  • irradiance caching

  • irradiance gradients: interpolates irradiance to save rendering time, works correctly with reflection and refraction (where shading noise reduction fails)

  • path tracing: fast when the number of ray bounces is small

  • reusable GI data to speed up rendering animations

  • Importance sampling: gives a huge speed up when rendering scenes with a large number of rays recursion

  • Light Portals: gives the ability to guide photons to where the camera is, resulting in better quality and faster rendering.

Image sampling

  • Several anti aliasing modes available Grid, Quasi MC, Random FSAA

  • 8 different pixel filters

  • Powerful geometry detection controls available


  • Caustics: fast caustics using photon maps

  • Fast blurry reflections

  • luminous polygons: any object can be a light source that illuminates other objects even if GI is disabled

  • Real 3D Motion blur

  • Realistic Depth Of Field effect (DOF)

  • Several tone mapping modes (gamma, linear, exponential, HSV)


  • instancing: ability to use models multiple times in a scene without additional memory usage

  • progressive preview display

  • multi threading, takes advantage of multi core, multi CPU, hyper threading systems (up to 128 threads)

  • GUI with predefined presets

  • dual platform license (Mac, PC)

  • Buffers output

  • Tone mapping

  • 64 bit support

  • PC and Mac dual licence

  • Unlimited render nodes

Software development kit is available for anyone that wants to port Kray render engine to another software. Please
contact us for more details.

Pricing and availability

Kray render engine is available immediately and can be ordered through web page for the price of EUR 319. It runs on Windows and OSX, 32bit and 64bit platforms, one licence can be used on one workstation with unlimited render nodes.There are no limitations about number of processors/cores workstation or render node have.
