YafRay Lighting Discussion


yafray-lighting-small.jpgAlvaro Luna Bautista pointed us to a great YafRay/Lighting discussion that has just recently been translated into English.

From his e-mail:

We just have finished the translation of a new YafRay document into English. The original is based on a lecture that Alejandro Conty gave last June.  That lecture was also based on this YafRay paper, although in this [new]document everything is much better explained and there are also some extra tips.  The document is not just about Yafray, it explains general concepts about raytracing and Global Illumination that are applicable to other similar render engines. Luis, Claws, and I have collaborated in this translation.

Yafray is certainly alive with documentation, and this lighting discussion is certainly a great addition to understanding YafRay and lighting.

About Author


Just a guy really into 3D, especially where Blender is concerned.


  1. I recommend it, it's a great documentation !
    It would also be nice to get a translated version for the Czech document referenced by UglyMike, it looks very useful.

  2. wow awesome, very informative documentation. i'll definitly read it. even if i read the using_yafray.pdf. thx cool work.

  3. This is great!!!

    I really needed this information....

    I am going to be able to get it with trial and error, I am sure...

    The only suggestion I have for the authors is the same I have for about 99.9999% of the tutorials I find regarding size/scale...

    In the lighting tutorial they constantly say "Small", "medium" or "large"...

    DEFINE small

    DEFINE medium

    DEFINE large

    The blender team has been nice enough to give us "UNITS" to measure things.

    in the tutorial they leave it up to random chance that the reader will ever be able to guess, that perhaps 1 blender unit is small... or 1 blender unit is too big.

    rather than just saying something like "the Yafray ray tracer was programmed from scratch with the scale of "1" blender unit to be equal to 1 metric meter. thus you should scale all things this way to get your lighting to work properly"

    Anyone know how many BTU's 1 blender point light with the power of 1 is in yafray?

  4. Hey I am a noob trying to become a pro and sooo very excite about Blender and YafRay. I have always wanted to do CG and could never afford the Maya or 3DX. And soon gave up till I found Blender. Saved my dream and now can’t wait to get better with time and practice.

    I downloaded YafRay but have no idea how it works or how to get my pics over into it so I can do some sweet rendering. If you can give me a tip or shoot me to the right direction or a tutorial on how it is all done that would be path.

    Blend on!!

  5. Our electroluminescent wire product has own invention letter of patent ( has picture introduce). We are applying international patent, product have very big different with other kind of. Have CE prove. We engage in EL and phosphor shine have 45 year histories. Our product safety, environment protection, benefit to health, save electric power.
    Product can be used for shine toy, enhance child's creativity, fancy.
    Can should be used for neon Advertisement lighting wire,lighting toys ,Christmas Day adorn, for example tree, garden, building.
    Can should be used for advertisement, for example bar.


    Flexible Neon Wire, also called Electroluminescent (EL ) Wire is the new generation product in global lighting and display industry. Wrapped by colorful plastic tube on its surface, it appears similar to common phone wire, emitting light along its entire length but without any heat radiation. It consumes much lower power, just 50-70% of LED lamp, 20-40%,rope lamp and 1-10% neon light.
    1. Indoor and outdoor Advertisement: written pattern for display window, door, furniture, wall, ceiling etc.
    2. Vehicle decoration: Internal and external car, ship etc., instrument, meter or data display.
    3. Safety sign and indication: Street, stairway, corridor, doorplate, exit and outdoor temporary danger zone etc.
    4. Toys, arts an crafts, sports items, clothing, electrical appliance, military equipments etc.

    1) Homogeneous light along the entire length with wide range of vivid color, great and comfortable to be seen especially in darkness for both human being and animal, also no influence on growth of plants. It’s clear and safe to be observed in distance at night when it’s been equipped on car door outline. It also can beauty the city night scene when applied on tree, grass etc.
    2) With characteristic of energy saving, environmental protection as well as safety, it has low power consumption, applied to voltage from 3V to 220V, also no heat radiation, can save national electric power sources greatly. As per present suitable application in indoor or outdoor low building , it’s able to save 15% darkness decoration power in cities. And decrease environmental temperature efficiently. It will not cause any environmental pollution whatever usage or be abandoned, especially can avoid serious lighting pollution in big cities. Due to its low working current , it has no harm to human body.
    3) It’s flexible, can be bent , knotted, cut , stretched, spliced etc. but lighting effect will not be influenced . Flexibility of EL wire is similar to common phone wire, folding angle reach more than 15 degree, maximum bending achieve 360 degree, and can be bent or stretched repeatedly . The length of EL wire is cut according to customer’s application but the homogenous lighting effect remain still the same.
    4) it come into continuous lighting length , featured in 360 degree multi color lighting, be made single color or combination of different colors on one single wire, animation effect is achieved by circuit control. It has different shape such as squareness, round, half round, flat etc. Single luminescence core or more luminescence cores is able to be combined to improve the brightness. Diameter arrange from 0.7 to 20mm or even bigger.
    5) To be fixed on decoration surface with transparent adhesive tape, glue, clip, thread nail, or plastic card etc. decoration surface include glass, display window, furniture, window, wall etc. It’s easy to be applied, no need of any professional instruction. Flat EL wire can also to be sewed on cloth, leather etc.
