Indoor Lights for Iray Renders

Hello,

for outdoor scenes I have been using HDRI very happily. For indoor scenes I don't like them.

There are now so many available. Does anyone here have experience of a number of suitable lights for indoor?

I would like both flexibility and speed (wouldn't we all).

I would be gratefull for advice.

    I use this http://www.daz3d.com/real-lights-for-daz-studio-iray

    for this scene I used 120W Fluorescent Lamp only

    This was using 8 Bulb 60Watt Presets of the same item mentioned before.

    Both good images and I'm wondering if the "lamps" used have better render times than a light-emitting plane, or if they are basically the same thing?

    Same thing.

    Zilvergrafix has noted in past posts that his render rig is fairly Cuda-rich (upwards of 3,000 cores, maybe more by by now). With that many cores, even emissive objects render pretty quickly. So it's all relative.

    They are beautifull renders, however, my Mac does not have an Nividia card. Are these lights likely to be slow to render using CPU only?

    Dont forget the ALR rig for indoor lighting as well. I can't recommend Marshians stuff enough:

    Young lady does amazing work and saves my poor light challenged brain a lot of headaches.

    nah, just 2880 Cuda Cores...for now. yep, it's fast with emitters, but slow when you use Architectural ON.

    on iRay is the same thing, the lamps  and plane primitives are 3d meshes with emitter presets, the render time is the same in both cases and, if some differences would be non perceptible.

    tip, I use more Watt units than candela or lumens.

    the minimal is getting +2500 iterations, and the grain will be acceptable.

    I recommend Painter's Lights, flexible, fast, really well done. I use them all the time.

    I just picked up Painter's Lights this past week and... I concur. AMAZING.

    thank you, I assume that they work well with Iray? If so I will take a look at Painters Lights.

    They are specific to Iray. I tried converting them to 3DL and, well. Not so good (too many things are different between how 3DL and Iray lights are set up)

    Great! Thank You!
