iray sample scenes
While I don’t have time at the moment to create any step-by-step tutorials for iray I figured a couple of sample scenes with some tips might be useful to get started with.
Scene 01: Basic scene illuminated by HDR environment, self-illuminated material (spiral geometry), and a photometric light (sphere). This scene isn’t really any different from how I would configure a mental ray scene, other than it’s using iray.

Scene 02: This scene is using a daylight system. This does work a bit differently than it does with mental ray. You’ll notice the mrSun/mrSky lights are actually disabled, yet it’s still illuminated. That’s because it’s using the environment (mrPhysical sky) instead of the lights. The daylight lights (mrSun/mrSky) are still useful for positioning the sunlight angle though. So if you move them, the light changes as you’d expect.
Adjustments are a bit different here though. I drag the mrPhysical sky from the environment to the material editor and adjust the Disk Intensity and Glow intensity to tune the sunlight brightness/hardness. And of course the non-physical tuning options of the physical sky or mrsky will adjust the blue/red tint of the light/sky.

Hope this help get people started with iray while waiting for some detailed/scene specific/step-by-step tutorials to start appearing.

Thanks for so useful information, as usual!.
Hi Jeff,
Firstly many thanks for your help over the years, you are Yoda of the rendering world.
I’ve just started testing iray and your sample scene runs very quickly on my Quadro 4000 6core i7 extreme 4.8ghz but when I try some of my interior scenes with mr sun system it takes an eternity for a simple room with a sofa in it?
Is it better to stick with Mental ray for larger interior scenes? I can see the benefits for products with iray.
Many thanks
See my Optimize Interiors with iray post and I also comment on using iray for architectural interiors in my Why iray thread.
Thanks Jeff.
